How to test Thermostat (4 contacts)

I have a Bosch dishwasher SGS6312GB/12 which dosen't heat up the water. I've checked the Hetare element which has a resistance of c.23ohms. The NTC Thermostat (4 contacts) microswitch breaks when I put it in hot water and makes when it cools down, there are how ever two other contacts. What do they do and how do I test them . They both give open circuit readings when tested with the other contacts

I'm probably sounding like a broken record, but id f its got buttons on the front and not a knob, its probably the control board. Unplug the unit or flip the breaker.Take off the outer door and the control panel by removing all those torx screws down each side, then pop that control board with all the wires out of the housing. once you have that in your hand, open the control assembly itself (should open like a book, into 2 halfs) once you spot the half without the buttons and lights, take that half out of the plastic housing and look on the back. If there is a burnt solder joint there (it will be obvious if it is) you will need to have that joint repaired, or get a new control board..bout $150 if memory serves. that joint that burns powers the heater, so its likely thats your problem. It can also cause some other isuuse as well, such as the time display freaking out (if you have one) Good Luck!

SOURCE: BOSCH DW burned plastic smell, common problem?

the black stuff you talk about is bitumen or tar this is used to insulate appliance keep heat in the tub and as sound deadening to muffle wash pulses as arms inside rotate.it wont be this that is smelling,a lot of these machines are fitted with a voltage suppresor to elimanate voltage spikes and smooth the current into machine when these start to fail they can smell of burning plastic and usually short out during wash heating they can be removed and the machine will work quite happily without it,you need to remove sidepanel on r/h/s to get to it if it is this it will look black and smell horrible the smell travels up the back of applianc thats wh it seems to come from bitumen cating.

hope this helps.

How do i check serviceability of thermostat and heating element on bosch dishwasher


Is the dishwasher connected to the hot water line? It should at least get hot water when it initially fills and then keep it hot when it operates.

Water-heating cycle
the water must be preheating , you must test the heating element + thermostat, otherwise the machine stop
Timer
test the timer, for defective, clean contacts, repair wires for broken, burn, or loose.

On full cycle when water turned off now not heating water


Hi Barry. Most of the times the problem is the temperature sensor located near to the heating element, at the bottom side of the appliance.

Before going for the sensor check pressure at faucet. Make sure that hot water is correctly connected and that there is pressure. If inlet is double, check water temperature at hot faucet. Test the appliance running hot water for a couple of minutes before starting the cycle.

If that is not the problem, then the heating element and thermostat must be removed from the appliance and tested. Testing is done reading impedance respectively across thermostat and element contacts. If any of the two parts returns Ohms infinity (circuit open), then the part must be replaced. If the parts comprised in the heater assembly are OK test wiring and timer board.

Operations that involve disassembling must be carried by qualified personal.

Water not heating up and not drying


Hello

If your dishwasher is not heating properly, troubleshoot the issue. You can often repair this problem and eliminate service fees.

Incoming Water
Most manufacturers recommend that the water coming into your dishwasher be at least 120 degrees Fahrenheit. If the water is too cold, then your dishes don't clean properly. Or the dishwasher must run longer to heat up the water. Test the water temperature by running the hot water on your faucet for about 2 minutes or until it gets really hot. Place a waterproof thermometer under the water. If the water is too cold, increase the water temperature setting on your water heater.

Thermostat
The thermostat is responsible for regulating the water and drying cycle temperature. If this thermostat isn't working, the heating element at the base of the dishwasher tub may not come on. Test this element by selecting the hottest temperature setting. Run the dishwasher on the shortest cycle. Let the dishwasher run for a few minutes, and open it up. If the dishwasher water is not hot or the drying cycle isn't starting, order a new thermostat from a parts dealer since this component is difficult to fix.


Heating Element/Drying Fan

The heating element heats up the water and air. Access this element by removing the bottom rack. It looks like a long black rod. If any part of this component is broken or corroded, you must order a new one. You usually cannot fix this element. The drying fan is located in the main housing of the dishwasher, and it blows air around your dishes to dry them. Check this part by disconnecting the dishwasher from the power supply and opening up the housing. Examine the fan, and see if any dirt or debris is preventing it from moving. Clean it. If the fan won't turn at all or if the motor is burnt out, order a new fan since it's difficult to repair this part.

Additional Concerns

If your dishwasher isn't drying your dishes properly, see if you have selected a heated drying cycle. An air drying cycle doesn't completely dry your dishes. Never overload the dishwasher, as this prevents heat from circulating around your dishes, keeping them from drying properly. Plastic and Teflon dishes don't usually completely dry. You must towel-dry these items.

My Bosch Dishwasher is not drying my dishes now. The model number is SHE44C05UC.


Hi there,

Unfortunately, it seems that the heating element has failed. The dishwasher uses steam to heat the tub to dry the dishes. I suspect your dishes are also being washed in cold water.

To check this, please run a regular full wash cycle. Allow the washer to fill with water and run for about 10 minutes, then open the door and feel the water temperature in the bottom of the washer. If the water is cold, it's more than likely the heating element has failed.

There are other possible faults which would cause the element not to heat, but these often prevent the dishwasher from completing the cycle. If the water is cold but the dishwasher still drains the water at the end - and completes the cycle - the heating element has probably failed.

Please try this simple test for water temperature and let me know if you need further assistance.

Regards,
BElectric

Bosch Dishwasher, model SGS6312GB/07. The water does not heat up so the dishwasher does not complete its cycle and remains in wash mode. The water has to be scooped out


press cancel/drain sequence to get water out-check owners manual.

Bosh exxcel dishwasher heater problem


Check with multi-meter for power on the heating element's tags. If it does get power, you should replace the heating element. In case of no power- you should replace the thermostat. Good luck!

Dishwasher not heating


It could be a malfunction heating element, thermostat or both. In most cases it's the heating element. Check with a multi-meter for 115/220V on the heater tags. In case you get this voltage there, you should replace the heating element. In case you can't read the 115/220V on the heater tags, check thermostat's for continuity (you should read a low resistance). In case you can't get any measurement. You should replace the thermostat. Good luck
