No Power Bosch SGV43A03GB Dishwasher

This is a fully integrated model. It blew the mains (13A) fuse and there was a strong burning smell.

The suppressor on the back of the power inlet block looked to be the culprit, it was charred at one end and had blown off a bit of the plastic insulation cover.

Replaced the suppressor, powered it up and the machine went through what looked to be the final rinse cycle OK (filled up, heated water, washed and emptied).

Started it on a new wash but it only went part way through the first rinse cycle and then seemed to stick, there was a repetitive clicking noise coming from what seemed to be both underneath the machine and the control box (I ran it in this state with the control box loose to try and identify where the clicking was coming from better).

Took the control box apart (3 clips) to see if I could see any signs of damage (solder joints or components) but nothing apparent.

Put control box back in, turned on power, no lights or anything. Rechecked connections, there is power at both sides of the on/off switch (leading to control unit).

Don’t think there is a separate earth fault causing knock on problems (read this in an earlier post) as I have a 30ma RCD on the whole house and it hasn’t tripped since this problem started (it’s very sensitive…).

Any suggestions? Could the suppressor blowing have damaged the control unit? Are there any other checks I could usefully do before replacing the control unit?

Thanks.
