Bosch Exxcel dishwasher problems

[Lesb]

I have a Bosch Exxcel dishwasher which only pumps water out of the top spray arm. There is plenty of pressure and I have stripped all of the pipes out and cleaned then. Does anyone know what changes the water supply to and from the lower and top washer arms and what can I check to see where the problem lies Thanks

Before you go any further go on the Bosch website some dishwahers From 99 to 2005 have been recalled due to a fault with the pcb. Yours has a fault on the solenoid on the heater box.

Many thanks for the reply

I've been on their web site and mine is a unit that needs the modified board so I've got them coming out to replace it FOC !

I will check the solenoid in the heater box which I thick sits beneath the dishwasher

Thanks once again
