My 10 year old Bosch Aquatech dishwasher seems to have developed a problem.
If the dishes are particularly dirty they come out at the end of the wash feeling grainy.
I think this is caused by the failure of the sensor on this machine to detect how dirty the water is at the end of the pre-wash cycle. It doesn’t seem to empty between the Pre-wash and Main wash.
Is there an easy way to check this sensor? Where is it located?
Many Thanks,
Ian

Hi
First things first 🙂
Remove the spray arms and thoughly clean the spray jets.
It may not be heating and/or recirculating due to low water level or heater may well have failed.
If heater ok, worth checking the usual solder problem on relay pin on module 😉
Worth checking the ribbed clear hose behind the lower panel below door. This can be removed and cleaned as it only o rings in either end.
The water matrix and the metering unit (both lhs behind side panel; get crudded for the sake of not giving the plates a quick swill under tap before loading.
The sensors are inaccesible tbh. Running hot cycles eventually may clear any crud.
Not draining in between could be down to not reaching temp or a tired drain pump. Check above first then move to drain thought.
Power off if you are to attempt any of this :plug:Greg

I’ve checked and cleaned the arms and top jet (this one was quite clogged)
Heating seems fine and water level is well above the filter.
The machine will fully drain in about 30 seconds so I guess the pump and ways are OK.
I’ll take a look at the other items whan I have time. Thanks
