Re: AEG LAVAMAT 74630 NO POWER TO NEW/OPERATIONAL DRAIN PUM
Just tried EMW but they don’t do AEG boards – shame really as much more reasonable on their refund if the board proves to be OK and not the problem.

Thanks for the pointer Steve. Will give them a call and find out more about them.
Re: AEG LAVAMAT 74630 NO POWER TO NEW/OPERATIONAL DRAIN PUM
Thanks again for your advice and input. I guess this might be down to the fact that there is a small tear in the rubber seal on the door/drum which, although it is at 90 degrees to the bottom, probably drips out water when on a certain cycle – I recently put too much powder into the machine……. had a flood so no doubt that’s when it started to happen. Guess replacing the door seal is a must if it ever works again.
So, I will have another look, take out the PCB, guess I will need the numbers off it anyway and look for the triac (just Googled it to see what it looks like!) though I didn’t notice anything that looked frazzled yesterday. Then it’s a case of marking up all the wires and sending off the PCB. The only frustrating thing is that the company that repair the modules charge so much even if the module is OK (ie you only get 25{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the cost back – so it will cost about £30 to find out it’s OK). Cheaper than a call out I guess and if it is still bust after changing the PCB it would have to be a new machine anyway. Shame the LaV 74630 is a good machine – made in Germany – has been on at least once, normally twice, sometimes 3 times a day!
Before I send off the PCB, could you please confirm that using the same make of pump, identical to the one I took off, but which is 34W instead of 30W would have no affect at all on the pump working? It’s just more powerful isn’t it?
Re: AEG LAVAMAT 74630 NO POWER TO NEW/OPERATIONAL DRAIN PUM
Worked out how to take lid of machine off. Two screws on back then it slides off forwards. Found the PCB inside a plastic box screwed to the inside right of the machine. Checked all the terminals and can’t see any burning or sign of damage. Pulled them on and off hoping to clear any problems with seating. The actual board was quite sooty – is that normal? gently cleaned off the soot.
Reconnected the power and put machine on drain cycle. The pcb was clicking but no response from the pump. The spin came in as normal. It is only the drain pump that is not taking a current. Can the problem still be the pcb. Is there any way to check to see if the pcb is sending a current to the pump or if the wires are bust (is that possible? They look ok). Don’t want to spend £49 on a reworked PCB if mine is OK and the problem is something else, but any ideas on how I can check please?
Any help really appreciated. Now handwashing and using the machine to spin and using the emergency drain pipe to let the water out!
😥 Is there some pressure switch that would be interfering with the pump?Re: AEG LAVAMAT 74630 NO POWER TO NEW/OPERATIONAL DRAIN PUM
Thanks so much for your reply! I have been scouring the boards to find same problem and thought the PCB might be involved. I think the PCB is is the complicated electronic circuit board? Think I will need to take off the lid to the machine for access to PCB? I managed to replace the pump by going in from the back but it was a squeeze.
Is there a way to test if the PCB is the problem before going ahead and buying a replacement please? Think there is a place that does reconditioned ones for about £29 (mm, that’s trade price – ex trade is £47) – does that sound right? Thanks for your advice.
Will the damage to the PCB be obvious if the pump has shorted it out?
