There are quite a few threads on here for Neff/Bosch dishwashers not heating with 1 in the display so it might be worth searching the threads for the same problem but here are the 3 things to check for 1 in the display and running forever…..and these are in order of probablre causes
1. Water levels – check left hand side pressure chamber and hose for blockages – these will give low water levels which = no heat which = no cycle progression. This can sometimes be heard when appliance is filling by a kerdunk kerdunk noise and brief operation of the drain pump .
2. Burnt out contact on control module – If module has been changed thi is unlikely but still worth checking for bad joints on the board.
3. Open circuit water heater – right hand side – should be approx 23 – 33 ohms
Hope this helps

There is a mod where you fit a metal ‘sheet’ over the evaporator which apparently acts like a blanket to keep more heat around the evaporator during adefrost stage.
Is it an icing up problem with the evaporator ?
If the FD number is after 8701 it won’t need the drain hole heater mod.
We tend to fit a new PCB as well as the timings for the defrost cycle has been altered i believe.

I hate these bloody web sites selling parts, …….
What , like this one ? 😆 😆 😆
….and water levels . Most common fault leading to 1 minute and not ending is blocked pressure chamber and hose causing low water elevels – Low water levels = no heating
I think F:31 is an overfill fault .
Put the machine on a normal cycle , empty , start it and see where the wat level stops at. It should only fill to about 2 inches above the bottom of the inner drum . If it keeps filling , then you have a problem with the pressure level system.
This is one of the new design machines i think. They actually open up like a clam shell…..with the top and white base pulling apart at the front and the tub gets ‘leant’ backwards to reveal the inner workings in the base.#
E24 could be caused by the drain pump cover (in sump) being out of position or loose. , blocked or kinked drain hose etc. It can also be caused by a stiff circulation pump .
There are a variety of tests that these appliances carry out prior to starting….and this is prob when the error code is appearing.
I’d be thinking about fitting a new door lock lads. I have the same fault a couple of times on the Neff version – sets the programmes ok , start led goes solid and counts down but no drum action or heater. Both times it was the door lock !!
I take it that it is a KGN then ?
It would be much easier if you can get it defrosted 48hrs beforehand by getting it switched off.
If the evaporator is really iced over , the white evaporator cover is a bitch to get off as the evaporator is iced frozen to the defrost heater which , in turn , is frozen solid to the cover itself……and it is quite easy to damage the cover and/or heater.
Are you looking at fitting the mod to prevent the evaporator icing over ?Could you mean a KGN rather than a KGV ?
If it is , it may need defrosting first .
Once defrosted , remove shelves and then two screws on rear panel . Take out rear panel.
Then remove two screws at top edge , holding in top evaporator cover . Once these screws are out the cover will slide forward….but only slide it forward approx 6 inches. Once it is in this position , you will need to reach behind it and unplug the defrost heater connection….i think its the 3rd one up of 4 . Once unplugged the whole cover will slide forward and out – Make sure the evaporator itself doesn’t come sliding out with it !!!
You’ll need to check the heating element for resistance and you’ll prob find its open circuit. The machine is waiting for the water to heat up…..which i suspect it isn’t doing.
The element is situated on the lower front edge of the tub.
Its not to bad a job to replace .PLEASE POWER OFF IF INVESTIGATING
Normally a blocked pressure chamber or inlet hose between pressure chamber and tub.
Check them out on the left hand side for gunge and blockages.
Contact BSH Appliance care and explain the situation . There is a modification that will cure the fault on the Fridge freezer.
If you talk to them nicely , you may be able to sort out a repair .Most likely causes of steam from drawer are :
1. Condensate valve open circuit
2. Drying fan not operating
3. Blocked condensor boxYou will need to check these3 items but if the overheat stat has popped , i’d be looking at the fan first and condensor box second .
It’ll be the flow rate sensor ( impellor jug 424099 ) that sits in line with the inlet hose. You’ll find it as a whilte circular component on the left hand side between the water matrix and the end of the inlet hose.
Power off when investigating.
