Bosch Exxcel - cold water

[mikec15]

Hi.
Our dishwasher has stopped cleaning as it is not heating the water properly. Have opened up the side panels and there appears to be some clogging in the water pipes on the right hand side of the machine, other than that, no issues are immediately apparent. I've cleaned out the waste filters and checked the drainage pipe. Any ideas on a fix?
Cheers,

If you post the model number (etched into door rim) then should be able to more specific

You should first check the resistance of the heater element(25ohms) on the opposite side (depending on model)

If there is poor flow then the heater will also not work so you should strip down the pressure chamber
and clean the transfer pipe to the sump.

Hope this helps

You can see some diagrams of your machine on the link below

you need to dissassemble the pressure chamber (0410) and also clean the
pipe from it to the sump(0430)

Check the resistance of the heater element(0440) if this is o/c then you need a new one.

you may also have a faulty jug impellor (0513) this meters the water into the
machine -this usually gives underfilling/overfilling problems though not pressure/circulation issues.
likley gunged up and cleaning the above will sort it........

After that its probably a fault on the control board.
