This is part 2 in the saga of the Beko WM74155LS which we had delivered on Friday.

So we got it all connected, retaining bolts removed and put a half load in. Dial turned to quick wash, temperature and spin type selected and pushed the start/pause button... and pushed the start/pause button... and pushed the start/pause button... and turned the dial to another setting, pushed the start/pause button... turned the childlock on then off again and pressed the start/pause button...

So I'm sure you get the idea that no matter what we do, the machine just will not start. As yesterday was a bank holiday in the UK, I rang Beko today. After going through all the usual pre-problem checks I explained what is, or rather isn't, happening. I was told that they normally tell customers with this problem to:

Turn the machine off at the mains.

Wait 2 hours

While holding the start/pause button, turn mains power on again

Do another (another?) half load wash

That should be the problem sorted

If that is the case, and I have to wait another hour abnd a quarter to find out, why isn't this mentioned in the instructions? There isn't even a whiff of what to do if your machine doesn't work. No mention even in the "Troubleshooting" section.

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Beko WM74155LS intermittently will not start a programme

The problem
A brand new Beko WM74155LS would often not start when a wash programme was selected and the start/pause button pressed. The lights were on and mains power was present. The machine did start occasionally after repeated button pressing, and after being left off at the mains for a couple of hours it worked once, but then failed again on the next wash attempt.
Likely cause
Intermittent fault within the machine was strongly suspected. The discussion considered a door not closed properly, a faulty door lock, or no water supply, but the reset only gave temporary operation and the original poster concluded the machine itself was faulty. The exact failed component was not confirmed.
What fixed it
Beko advised powering the machine off at the mains for two hours, then powering it back up while holding the start/pause button, as a reset attempt. This only restored operation temporarily. The recommended next step was to report the appliance as faulty and have it checked by an engineer.
Checks to try
  • Transit bolts had been removed
  • Water supply was connected
  • A plastic bung in the inlet was removed
  • Door was checked and latched properly
  • Machine was powered off at the mains for a couple of hours and then powered back on as advised by Beko

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

If lights are on and power is clearly ok then the main cause of a washer not starting is the door not closed properly (or door lock faulty), or maybe even no water available to machine. If the latter though, it should work on a spin only programme! It's very rare for a washing machine to be faulty on delivery.

Thats what we thought as well. The water is connected ok. There was a little plastic bung in the inlet which had to be removed and which the manual didn't mention. The door is closed and it latches ok as well. The machine has started a few times after random button pushing but thats a rarity. Some people online are saying just to remove it from the mains for a few hours to reset the logic board, which would fit with what Beko have said, so we'll try that,

Well I waited a couple of hours then powered it back up and it worked first time. My wife went to do another wash a couple of minutes ago and its not working again. It has to be a fault with the machine.

You've taken all reasonable steps so it's a case of reporting it faulty. They'll most likely insist on sending an engineer, no one will accept something's faulty without an engineer checking it's not a user or installation fault first. Have you checked if it starts on a spin only programme?
