Fault Notes

• FillingAfter the initial drain period, it is normal at the start of a cycle for the machine to pause for a period before filling.

• Heating ElementAn open circuit heating element can display either the heating time out fault code or the open circuit heater fault code (F8 & F10), depending on the cycle in progress or the phase of the cycle when the heater fails. If a dishwasher has an open circuit heating element, the machine may run for up to 75 minutes before a fault code will display.It is recommended before a module is replaced or when the fault is not obvious, the heating element is tested for continuity and resistance to Earth at its terminals, with the heater disconnected.

• Programme TimesThe times in the handbook and displayed at the start of the cycle, are average times and will be affected by the following points:• Inlet water temperature below 19°C • Tab option enabled• Water hardness setting set to positions 4 or 5• Condition of the heating element (limescale built up)• Excessive foam caused by using tablets with a small or light load.

NOTE: - The display is not a count down timer. It is normal occasionally for the same time to show for an extended period.

• Machine Starts up for a few minutes when not in useThe machine inlet valve is 'letting by' and water is leaking into the machine when not in use. Providing the machine is plugged in and the door closed (it does not have to be switched on), once the water in the machine is enough to operate the pressure switch to full level, the machine drain pump will energise until the pressure switch resets to empty (plus 30 seconds).

Note: - Fault code F2 displays if the water letting by is fast enough to be recognised by the water turbine.

COMPONENT DESCRIPTION

ModuleMounted behind the plinth, this is an electronic device that monitors and controls all devices within the appliance. If replacing this module, refer to the Module Programming section on in this manual.Both DEA700 and DEA603 Modules have been used in Production. The DEA700 Module was used in Production up to Industrial Code ending 2500.From Industrial Code ending xxxxxx2500, the Electronic Module changed to a DEA603 variant. Note: (xxxxx is the Dishwashers Commercial Code).DEA603, is a Stripped variation of DEA700. There is no change to the Programmes or Operation of the machine.The 2 module types ARE NOT interchangeable, and the correct settings file must be used with the correct module.

Fill ValveThe appliance has an electromagnetically operated solenoid valve, which is connected to the water supply.

Water TurbineThis is situated at the bottom of the Air Break. Consisting of a fixed reed switch and a magnet fitted to an impeller. Unlike previous control systems, water fill is no longer dependant on the operation of the pressure switch. The turbine generates a series of impulses as the water rotates the impeller vanes.The control module translates these impulses into litres of fill water (268 impulses is equal to 1 litre of water). The turbine also regulates the maximum amount of water that can enter the tub, therefore acting as an overflow device.Note: Machines with DEA603 Module fitted. If the Turbine senses a fill rate less than 0.9 litres/minute, the fill will be measured by Time. (Using previous Stored History of fill times)

Pressure SwitchThe Pressure Switch confirms to the Module the overall volume of water inside the tub and signals if the Heater can be turned on or a Fault Code Displayed. (see page 6)The pressure switch and associated wiring is Low Voltage (12 volts and 10 mA) with RAST 2.5 connector.The pressure switch indicates the full state only (appliance filled with water).Empty level is signalled when the pressure switch is not signalling full.

Anti Flood Device

Pressure Switch

18 of 39

Service Manual UK English

Indesit Company

Consisting of a polystyrene float and microswitch. An excess of water in the base panel operates the float switch sending a signal to the control module operating the drain pump and displaying a fault code on the console.

Detergent, Rinse Aid Dispenser

The dispenser fitted to these models works differently to dispensers previously found on Hotpoint / Indesit Dishwashers.

Operation of Detergent Dispenser:The dispenser incorporates a solenoid valve at the rear which, when activated, opens the dispenser to release the detergent and at the same time releases the rinse aid.The dispenser is activated:1. The Solenoid is energised for one second, to release the detergent; the rinse aid will not be released

in this short space of time, because of its viscosity.2. Once or repeatedly for a fixed duration of 10 seconds to release the rinse aid, depending on the

setting adopted by the user. Each time the dispenser is opened, 1.5 ml (1.5 cc) of rinse aid will be released.Possible settings:0: Off (no rinse aid is released)1. One pulse is generated, releasing 1.5 ml of rinse aid2: Two pulses are generated, releasing 3 ml of rinse aid3: Three pulses are generated, releasing 4.5 ml of rinse aid4: Four pulses are generated, releasing 6 ml of rinse aid.

ADDITIONAL COMPONENTS INFORMATION

HeaterThe heater is encased in a metal housing with integral safety cut-out and fuse. It connects to the Circulating Wash pump housing via a bayonet fitting. Refer to the Circulating Wash Pump description.

ThermistorSituated on the sump. A temperature rise in the water is converted to a changing resistance value.A rise in temperature will give a lower resistance across the terminals of the thermistor; the control module monitors this value and when it is the same as that as defined in the programme selected, the module will advance the programme out of the heating stage.

Regeneration ProcedureUnlike previous models Regeneration is not carried out during every wash. The Control Module counts the number of Litres used since the last Regeneration.The volume of water (in Litres) used between Regeneration is dependant upon the Water Hardness Setting stored in the Control Module. (Refer to "Setting the Water Hardness"). See Chart below.

Regeneration Sequence1. Regeneration valve activated, after 2 seconds, the fill inlet solenoid is opened to allow water flow,

water flows from the inlet through the salt and the mixture of water and salt reaches the resins.2. Solenoid valve closes (the inlet valve and after 2 seconds the regeneration valve).3. Pause for 10 minutes.4. Fill with 190cc of water (same procedure as step 1.).5. 5 minutes pause.6. Starts resin wash. Between 1 and 2 litres of water flow directly through the resins (Inlet valve is on,

regeneration valve is off.).7. Drains

Note: Regeneration time is hidden within the cycle so does not affect programme times.

Aqua-Stop Inlet ValveThe Aqua stop inlet water valve is located in the tap end of the fill hose. In the event of a split fill hose or the machine leaking, water will fill the base tray and operate the base float switch, which will signal the module to switch off the inlet valve.

Low Salt WarningAn Optical Sensor is fitted to the salt container where the presence of salt breaks the beam in the sensor. When the level of salt is below the sensor level, the receiving sensor receives the light beam from the sending LED. The Low Salt warning lamp is switched on 6 washes after the sensor signals the module.The sensor position is not at the bottom of the salt container because of possible false readings caused by impurities that collect in the bottom of the salt container.

Low Rinse AidA float is fitted into the rinse aid dispenser and when the level of the float is near the bottom of the rinse aid reservoir the float will trigger a signal to the Control Module to turn on the Low Rinse Aid Warning LampAir Break AssemblyLocated on the right hand side of the machine.The Air Break Assembly carries out 3 functions:1. Stops filling water siphoning back into the mains

water supply.2. Vents the Steam from the dishwasher tub.3. Diverts 3% of the hard water fill into the tub to

avoid the water being too soft which could cause excessive foam.The Air Break also holds the regeneration valve and the Water fill turbine.

DryingThe Natural Drying System uses Residual Heat and Rinse Aid to Dry the loaded dishwasher.During the Drying Phase of the cycle the Water reaches a very high Temperature 70°C,. Drying is carried out in 2 steps both with the machine paused (Circulating wash pump off)

GENERAL DISHWASHING INFORMATION

NOTE: - Many faults occur over along period of washing incorrectly. Correcting faults may not immediately cure a problem, e.g. several washes may be necessary to give better results.

POOR WASH RESULTSA variety of factors influence wash results and some of the more common are listed below.

A. FOOD OR STARCHY REMAINS LEFT ON CROCKERYMay be detected by running the tip of a finger over the surface of a dish or by wiping with iodine. This gives a blue/black colour to even the smallest trace of starch. Dried on starch or food soil should be washed off manually before placing items back into the dishwasher.

1. Food remains not removed prior to washing Ensure that surplus food is removed and that heavily encrusted or burnt on remains arepre-soaked.Ensure that Pre-Wash Programme is used if soiled dishes are being stored in the machine prior to washing.

2. Spray arm nozzle blockageCheck spray arm and check that the strainer is seated down correctly.

3. Deposits on cups and glassesDeposits of a sandy like substance etc., in cups and glasses in the upper section of the basket which looks like resin are generally caused by the spray arm not functioning properly.

Possible causes of spray arm inefficiency:Loading large or tall items in the lower basket which stops the arm revolving.Upper spray arm split along seam.Upper spray arm blocked.Under dosing of powder causing foam and reducing upper spray arm water pressure.Blocked strainers reducing water to circulating pump, therefore reducing upper spray arm water pressure.Low water quantity in machine.

4. Poor arrangement of load or overloadingEnsure that loading allows sufficient force of water to reach all dishes.In certain cases it may be necessary to leave some spaces empty to ensure good results.

5. Blocked filter or kinked drain hoseEnsure that these items are satisfactory otherwise excess food soil will be present in the machine.

6. Low wash temperatureCheck that correct programme is being used and that the thermostat is operating at the correct temperature.

7. Insufficient detergentFood soil may not be completely loosened and will not be kept in suspension in the water.If in doubt, too much detergent does no harm, but too little in the long run does.If dishes are heavily soiled add extra detergent. Remember - too little detergent causes foaming.

35 of 39

Service Manual UK English

Indesit Company

B. WHITE COATING ON DISHES AND INSIDE THE MACHINE1. White coating or scale

Detergent not only loosens the remains of food but, together with the calcium salts in the water, forms water-soluble compounds which prevent the appearance of the white calcium coating or scale. Insufficient detergent may result in a white coating on dishes and the machine interior.Unsoftened water can also cause this.Coatings can often be removed by the following:Take approximately 100 g of Citric Acid, a white very acidic powder which can be purchased at chemists. Put the dishes which are to be treated into the dishwasher and fill the dispensing container with Citric Acid instead of detergent. Then, switch on a normal programme (not the Economy programme). The container does not take the whole amount of acid powder so interrupt the programme before the start of the main washing cycle and pour the rest into the main body of the tub or the inside of the door.

2. White coating on dishes that tastes of saltPossibly caused by a poor seating regeneration valve or, most likely by a defective salt cap gasket.

C. WHITE CLOUDY FILM ON GLASSWARE (THAT CANNOT BE WASHED OFF)This is probably a surface deposit known as ‘silica scum’ or ‘detergent scum’ which can sometimes form by precipitation of one of the components of dishwasher detergents.The film can be scratched off with the tip of a needle (unlike etching). Unfortunately it can only be effectively removed under laboratory conditions. However, the following will prevent or slow down the deposits: -

1. Use less detergent where possible i.e.: when washing medium to lightly soiled items.2. Do not use poor quality detergent.3. Make sure that the rinse aid setting is correct. Lack of rinse aid could accentuate the problem.4. Use a liquid rather than a powder detergent (for dishwashers) particularly if glassware is constantly

being washed.5. Take care not to overload machine.6. Avoid washing poor quality glassware if possible.7. Check the salt regeneration setting is correct for the water supply.8. Check that the machine is filling correctly.9. Check that the machine is rinsing correctly.10. Check that the softener by-pass is working correctly.11. If the dishwasher has programmes of less than 65°C, use these in preference to 65°C programmes

when washing glassware.

D. WHITE DISHES TURNING PINK1. Caused by a chemical reaction between dishwasher detergent and porcelain. This porcelain is not

dishwasher proof.2. Formation of silicate scum on the dishes caused by using insufficient detergent. Silicate scum absorbs iron and/or Manganese which is present in all water supplies. This colours the

scum light brown or pink.

Service Manual UK English

Indesit Company

E. POOR DRYING1. Correct amount of Rinse Aid

The purpose of rinse aid when added to the water of a final rinse is to allow the water to run off the dishes as a complete film so that no water-run marks or calcium are left. To enable this to happen it is essential that the correct amount of rinse aid is dispensed. Too little does not reduce water tension sufficiently.Result: The water film breaks up into streaks which make shiny and clear drying impossible. After all the rest of the water has evaporated, marks are left which are especially noticeable on glass and cutlery as well as on items made from stainless steel.Too much rinse aid leaves smear marks. As a result, the dishes look and feel greasy.

Setting GuideSet dial to approximately mid position. From experience it is advisable to start with too little and to increase the amount until perfect results are obtained. This can be verified by holding the plate surface horizontal to incidental light at eye level. An even shine should be observed.The automatic rinse aid dispenser should then be adjusted accordingly.

2. Opening and closing door during dryingAllows hot air to escape and affects drying efficiency. Noticeable if the door is opened immediately the programme ends.

F. DAMAGED DISHESChipping off the edges is not usually due to them rattling against one another during washing. normally the weight of the dishes is sufficient to withstand the water pressure. Normal daily use of dishes causes microscopic cracks around the edges which fill with water during washing. During the heating period the water in these cracks expands and after several temperature changes the chips may break off. Chipping may on odd occasions be caused by overloading or by loading tightly together so that they cannot expand during heating.

G. DAMAGED GLASSES1. Cloudy stains not caused by poor washing or drying, may be due to ring structures in the glass.

These are minute cracks due to stress created during the manufacturing process. Particles may be washed off by hot water, leaving the surface with an etched and cloudy look. Similar results occur during hand washing but by using lower wash temperatures and milder detergents the effect takes longer to show.

2. Etched glassware can also be attributed to 100% softened water that is produced from a water softening plant that may be installed in the home. In this instance the customer can negotiate with the manufacturer of the softening plant to install a by-pass system to feed back approximately 5° of hardness into the water supply, or put the appliance back on to the mains water supply and use salt as required.

H. CUTLERY TARNISHING / DISCOLOURING1. Silver cutlery tarnishes when exposed to air. Stainless steel cutlery may show a coating on its

surface after several washes if water has been allowed to evaporate on it, e.g. if incorrect dose of rinse aid is used. Electrochemical reactions also have an effect and mixing various grades of stainless, bronze plated and silver cutlery will cause problems.

2. Nickel Silver (German Silver) is an alloy of copper, nickel and zinc, and when subjected to heat in dishwashing solutions the metal acquires a yellow colour. Maintaining this alloy in attractive condition requires frequent polishing and it should not be washed in a dishwasher.

3. Pits and rust marks on stainless steel cutlery can usually be attributed to inferior quality stainless steel or the finished article not being highly polished during manufacture.Certain food soils have a damaging effect on the protective coating of stainless steel, particularly foods containing vinegar, fruit and ordinary table salt.It should be noted that stainless steel should not be left in the humid atmosphere of the dishwasher for too long after the end of the programme, since this denies the protective coating the healing effect of oxygen.

4. Bronze or bronze plated cutlery is subject to rapid tarnishing and should not be washed in the dishwasher.

J. ALUMINIUM COOKING UTENSILSBright aluminium utensils may discolour or tarnish due to alkaline attack caused by certain minerals in the water. Removing these utensils before the final heated rinse should prevent further problems.Certain coloured aluminium utensils may discolour and should be washed manually.

K. RUSTING INSIDE THE MACHINENormally caused by migration of rust from non-stainless steel slivers alien to the machine or from external non-stainless steel nuts used for fixing heater clamps. General surface rusting may occur along the seams of the tub and can usually be removed by using a proprietary cleaner like Solvol Autosol or 3-in-1 Chrome Cleaner.

L. INTERNAL WHITE PLASTIC PARTS OF THE MACHINE TURNING ORANGE OR PINKDark red coloured earthenware can sometimes produce this effect by migration of the colouring. More common, is dishware being loaded with large amounts of tomato ketchup / juice present or the precipitation of the iron content in the water causing staining because of insufficient detergent and/or rinse aid dosage. The staining is not harmful but cannot be removed.

M. RAINBOW COLOURING ON STAINLESS STEEL INTERIOR AND COOKING UTENSILSUsually caused by consistent underdosing of detergent, particularly if liquid detergent is being used.

N. BLACK MARKS ON CHINAUsually caused by metal marks from spoons and knives. It can normally be removed by soaking the china in a mild bleach solution and washing or by gently rubbing with metal polish, wiping dry then washing.
