Sorry, I’ve been busier than I expected.
I just searched for a blinking light on a Beko, and this was one of the suggested results:
Water supply issue
A flashing light or tap symbol on newer model washing machines could indicate a water supply issue.
The other suggestions had either error codes or specific buttons flashing.
Assuming that the water supply is ok, that could suggest a problem with the pump, or just the pipe. Double check the tap on the pipe, and that the pipe is not blocked or kinked first, as they are the easy fixes.
I don’t know how to test much with a multimeter, but my next step would be to unplug the machine and turn off the water, and check the water flow inside it. Look for any blockages or loose connections, being careful around the electrical components, just in case.
My washing machine has the water feed at the top of the back, and it feeds through the soap drawer, then into the drum. Those pipes are fairly narrow, so would be worth checking too 👍
It may not be the water supply, that’s just what I found based on a flashing light on a Beko. If you search with more specific information it might give you a different answer. Some of the options were for if the start button was flashing, for example.
I still think that your best bet is to post to a DIY community here and give as much information as you can, like which light is flashing and if there’s any writing or a symbol near it, what happens before and after you get any problems, like does the machine drain, or is the water trapped.
Any information could help someone to pinpoint the issue, even if they don’t have the exact model :)
