Bosch dishwasher SGS66E0

[Oldtog]

Hi one and all.

Does any one have good knowledge of Bosch dishwashers? I thought I had reasonable knowledge of them until I came across the model SGS66E02GB/35 😳

Apparently the programme stops one minute before the end, and when I tested it I found the drain pump to pulse. The customer had looked the fault up on the net and he (it had to be the man of the house) said to me it was the electronic timer at fault. Not having the time to spend waiting for a prog to finish I thought it expedient 😳 to agree and to be honest it sounded to me as if it may well be the timer, especially after I had checked the air-break assy etc to be clear and no pipework restrictions.

Today I fitted a replacement timer and this afternoon the customer (the lady of the house) rang and said it is still doing what it was before 😳 😳

So, do any of you have any ideas, to be honest I am so run ragged with work since last September I do not know whether I am coming or going, been or went or where to. So the old brain box is a bit addled at present (how sad I know) :rolls: .

If any one can help

Many thanks

Does it actually stop one minute from the end or does it show a number one in the timer and takes ages to do the cycle – A number one in the display normally means one of two things –
1. Heater o/c or….
2. Low water fill levels on 2nd fill due to crudded up pressure chamber/blocked ribbed hose between pressure chamber/main sump. Low water levels means no heating and so extended wash times

Hi nomadPaul,

The customer says there is a number one in the display and takes a long time to finish, but they cancel the programme anyway, so you might be hitting the nail on the head there.

I removed the air-break with the feed tube to the base of machine and cleared that (slight crudge). I thought this may have been the cause of the drain pump pulsing (you never know) but it made no difference at all to the drain pump action, so I thought it may be timer related.

I will have to check the heater out on my return visit, I confess that never crossed my mind though (thanks).

Any other thoughts would be welcomed.

Re: Bosch dishwasher SGS66E0

A lot of Bosch dishwashers have ‘pulsing’ pumps so that would prob be normal. If the heater is ok and the water heats up on the initial cycle of a wash , i’d be looking at the pressure chamber on the bottom rhs corner of the LHS side chamber. What happens is that after the initial fill , the pressure switch is made to let the appliance know its full of water but if crudded up , it sticks in this position so the appliance thinks its still full at the beginning of the next fill cycle so won’t fill properly .
Hope this helps

Hi Trotter,

My customer is away until mid next week, also I do not work weekends 😀 for I need time to my family etc.

You can allways inform your customer you are looking into the the problem for it is an unusual one and will let them know ASAP the cost etc.

I hope this helps 😉 .

Re: Bosch dishwasher SGS66E0

Hi, sorry for not getting back sooner, everything is a blur, at last a break in work (for a few days anyway) 8) .

OK, fault is now cured and customer is well pleased (for now). I removed the air break unit to remove the pressure chamber unit. Strip and flush out this unit, refit all and test. Way hey no more probs 😆 😆 .

Many thanks nomadPaul, appreciated 😉 .
