For the last few weeks the cycle times that come up are 91-96 mins. Before that they were 86-90 mins
The only other problem ive found is that when on a eco cycle wash (50 deg) the dishwasher doesn’t empty properly and there is ~3/4″ watre in the bottom.
this drains completely if I restart the machine and then halt the cycle after a couple of mins with the 2 key stop .Anyone able to give a likely diagnosis ?
Anything to worry about?Re: Bosch Hydrosensor cycle times
Almost all run-time problems are caused by under-filling issues. Insufficient water will not pressurise the heater switch properly, thus extending the wash times.
Specifically, you need to check the transfer pipe in the front left hand corner of the machine, and ideally the chambers connected to the water matrix on the left hand side of the machine. All should be spotlessly clean.
Power off if you intend to deal with this yourself.

Re: Bosch Hydrosensor cycle times
I have experienced extended cycle times and insufficient water to wash – all happened rather suddenly. Not sure what caused it. Water supply to the machine seems good and no blockage there. Cleaned out the machine and no blockages but the pressure is insufficient coming at the bottom and insufficient to drive the spinning ‘washer arms’. Penguine45 refers to ‘the transfer pipe and chambers to the water matrix’. Are these inside the machine and accessed from the left side panel? These just need clearing out do they? And then everything should go back to normal?

It’s rather an old post you’ve tacked onto here. Lots of water under the bridge and through the dishwasher since those times. Though access for the most part is after the side panels are removed but essentially you’d best provide us with the full model (ENR) number of your specific appliance. It could well be that the water point on yours may be the problem? Model number your next move on that please?
Re: Bosch Hydrosensor cycle times
Hello there, I have a Bosh Hydrosensor NER number NSRS5602GB/02. When I opened up the side, the chambers were reasonably clean and free flowing. But I found there was virtually no water and I suspect the mains water supply switch (part 220319172) which is accessed through the small plastic back panel at the back is at fault – or the program brain which activates it. Hence, perhaps, insufficient water. Do these inlet switches often go or might it be something more serious?

I don’t quite know water you mean by inlet switch or recognise the part number (not a recognised Bosch number) you mention. If you mean the water inlet valve (directly connected to the inlet hose) then yes they do fail but usually when they do no water passes through.
Presumably the large water inlet matrix is empty of water is it? In which case the drain valve in the salt container could also be a suspect.
Re: Bosch Hydrosensor cycle times
Yes, I mean the water inlet valve – no water seems to be passing through. Yes, the larger water inlet matrix is empty. But if no water is coming in I suppose the inlet valve is the starting point and the thing to change first?
Re: Bosch Hydrosensor cycle times
Yep, quite agree about replacing the inlet valve. That’s assuming of course that water is getting to it in the first place through the hose and the fine mesh filter in the valve isn’t just blocked with silt?
Re: Bosch Hydrosensor cycle times
I checked the valve and cleaned it and it was not blocked. I have ordered a new valve and hopefully that will work. Fingers crossed and thank you for your most helpful advice.
Re: Bosch Hydrosensor cycle times
Hello there, I replaced the inlet valve with a new one. The water pressure from the mains water supply is good. Water is still not coming in…. with the side panel off I can see no water entering the water vessels. When I do manually add water in the dish sump area, the dishwasher runs fine. So any ideas why the water is simply not coming in?

You say you checked the valve but was the coil open circuit? I guess not and that being the case then no power is getting to it in the first place. You’ll therefore need to trace the supply back to the PCB to find out why?
Could be : rodent damaged wiring harness (mouse droppings evident?) faulty float micro switch or PCB?
