Bosch classixx maxx diswasher

[Monkeyboy10]

Hi, I have a Bosch classixx maxx dishwasher and it’s doing the most bizarre thing ever.
On ANY cycle, it will fill, heat up fine and go through the wash cycle. The problem appears to be when it’s going from the wash to rinse cycle, it pumps out fine after the wash cycle and as it is about to go into the rinse cycle it pulses and then the power lights all go out for half a second. They all come back on and then pulses and the lights go out again. So on and so fourth… it doesn’t get to the rinse cycle. I am able to reset the dishwasher during this and allow it to attempt to pump out and finish the programme.
I’ve checked the pcb for dry joints etc, all looks fine.
Any ideas on where else to start looking ??
Any help greatly appreciated..
Thanks in advance.

Few thoughts: Drain pump worn and sticking. Impellor Jug or the PCB ???

Re: Bosch classixx maxx diswasher

Had another quick look this morning and also noticed that the upper spray arm wasn’t turning.
Stopped the machine and added water manually and the arm was working again.
Looking at other posts this is possibly caused by not enough water entering the machine during filling…
It did however “do the pulsing thing” after wash cycle still.
The inlet valve and filter look OK, is there any way of testing it and also the jug impellor as suggested above…
Once again, thanks in advance..

Ah! Thanks for the further detail. You need to replace the impellor jug.

UPDATE……
Fitted the new jug impellor and that’s fixed the top arm not rotating, thanks..
The original problem still exists though, it won’t finish the cycle and still pulses with all lights going out for half a second.
I have noticed another funny going on with this machine that’s going to be launched into a skip very soon!!.
It will only heat up if the door is opened after its filled up…
If the door isn’t opened, it won’t heat up, open the door after heating and it will heat up fine…
I’ve taken the pcb out once more and looked closer but still haven’t found anything looking remotely burned or dry…
Don’t think I want to be spending another £80+ on trying a pcb…
Will get one if it cures the fault though… wish I could find a cheap 2nd hand one..
Any thoughts…

Thanks for your help, can’t really justify spending good money after bad on this…
