smeg dishwasher pulses

[bzz67]

DI 612a

almost goes through the whole wash cycle, doesn’t matter which wash you choose. near the end of the cycle the circulation pump pulses on for about 5 seconds then off there is an audio beep then silence for a few seconds, then it keeps repeating this until i reset, it then pumps out fine.
when this pulsing is occurring the solinoid on the detergent dispenser clicks on and off.
seems like a pcb fault to me, checked it for dry joints or burn marks but it looks fine.

hopefully someone has seen this before.
cheers

Re: smeg dishwasher pulses

despite the solonoid on the dispenser clicking, it could still be the problem, connect up any old valve coil to prove this.
