Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries
OK when you switch it on do you hear the pump running but nothing else happening?
OK I need you to check and see if you have water in the base of the cabinet (not within the appliance) this will mean you will have to remove the kickstrip and have a peep within with a torch
ie not in the sump but rather in the bottom of the unit where there might have been a leak
OK if you look inside you should be able to see a round plastic thing with three wires going to it screwed to the base with a polystyrene float assembly inside. Can you check that the connections to the switch are not melted and that the float is free to move (electric off first please)
Hang on a mo just checking something ~
If you click on the link above this will give you a picture of the NTC sensor ~ this is the thing that measures the temperature of the appliance during wash. What you need to do is check that the cables to this sensor are sound and not chaffed and are being routed back to the main facia pcb. The fault code 50/eco indicates that this is faulty but can also be the cabling. I'll dig out the diagram and see where it is fitted and come back to you later. Had to check that the base and flood protection was OK first ~ Ian
Just trying to get another supplier who may sell direct to you
OK this should do ~ http://www.beko-spares.co.uk/search/?c=0&c2=0&search=dw601&page=2 the part you need is part number(###) ###-####NTC sensor
Hope that has been helpful if so kindly rate my service ~ Ian
I'll come back to you with where it is shortly just trying to find the diagrams ~ thermistor is the same as a ntc
Hi, did you manage to find anything? Thanks.
Hang on just digging out the illustrated diagram
OK heres how to do it ~ firstly remove the appliance from the cabinet, disconnect all pipes and electric and (towels at the ready) tip it over on its back. Remove the base taking care as there is a flood protection float and switch screwed to the base (either unscrew it or carefully noting position remove the cables from the switch) You can now see the sump area, the ntc thermistor is pushed into this sump. Remember my earlier point, check that the connection cables to this ntc are sound. Replace the ntc and reconnect ~ reassemble the appliance and test whilst you have it out ~ make sure that the cables to the flood protection device are not charred and that there was no water in the base. Good luck ~ If you need further help give me a buzz, kindly rate my service when you are happy with things as I cannot close down the job until rated. Thanks ~ Ian
OK, I have the part on order but it may take a few days to get here, so I can't complete the repair immediately . Your instructions seem perfectly clear, and I'm happy to sign off. Thank you very much.
Hello again. I have replaced the NTC but the dishwasher is behaving as before. Flashing light no 3. I ran the test cycle again and got no error codes, and in fact if the NTC were still the problem wouldn't it show up on the test cycle? Wires all look clean and in good condition. In fact the whole thing looks pristine. What next?
OK when last you put it on did you get any heating of the water? The fault is associated as we mentioned earlier with measurement of the water temperature. Have you now got some hot water inside? Im assuming that you are not still locked out and have no ability to start the program?
Any progress? We are getting fed up with no dishwasher and will call an engineer soon if we can't get this sorted. Thanks.
Try this press and release the 50 button and tell me what happens ?
There isn't a 50 button; only a 50 light, which flashes. There is no response to the programme selector button when pressed.
Yes. Have to go out now, back this afternoon.
Had another good look around the cabling, which seems sound, and have decided it's time to call in an engineer as it's pushing the limits of my competence (and time). Thank you very much for all your help.
Finally, finally sorted. Both main PCB and control board replaced. Culprit seems to have been a dodgy fused switch at the wall which fried both boards.
