Beko Wm5100W Slow/low Water Fill

Hi folks, hope you can offer a bit of advice. I've had a wee look around and the advice seems pretty good in here!

I've got a washing machine that almost lets no water in the drawer. Result is almost no water in the machine. Manual says it should take a total of 51L overall... no chance!

I've performed a few checks:

Water inlet valve / hose - no problems, good pressure, good flow.

Filter in back of washing machine inlet - no problem, clean - took out and cleaned anyway.

I noticed when I took the filter out that there is what looks like a black rubber stopper with a small hole in right at the back of the inlet on the washing machine. I'm wondering if this should be there? I mean it's a hole smaller than a pencil width, or thereabouts. It seems like a silly hole to push water through.

We inherited the washing machine with the house, and upgraded the plumbing since... so I was curious if this was some type of pressure enhancer used when they had a water tank (small hole increases pressure, but reduces amount of water taken in). Can I remove it? I can't find anything relating to this in the manual, and have no idea what to call it.

Other info - only cold water hose attached. I can also add water through the drawer and it does fill the WM, so it's not going down the drain directly. It really is a low flow somewhere between the cold water INTAKE on the back of the WM, and the drawer.

Any takers? I know this is a basic machine, but it seems silly to replace it completely when it appears to work fine in all other respects (aside from the mammoth ~2hr 20min washing cycle)...

Thanks!

Solution Summary

AI-generated from this discussion

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

Beko Wm5100W very slow water fill likely due to inlet valve restriction

The problem
A Beko Wm5100W washing machine was reported to let only a trickle of water into the drawer, leading to very low fill levels and long wash times. The owner confirmed water could be added manually through the drawer and it did enter the drum, so the issue appeared to be on the inlet side between the cold water connection and the dispenser.
Likely cause
The black rubber insert behind the inlet filter was identified as a normal pressure-reducing insert for the cold valve and not the fault. Based on the discussion, the most likely cause was a faulty or internally restricted water inlet valve, possibly scaled up, after supply pressure, hose flow and inlet filter had been checked.
What fixed it
No confirmed repair was carried out. The strongest recommendation was to suspect and investigate the water inlet valve if the incoming supply, hose routing and filter were all satisfactory. The owner indicated they might replace the machine rather than repair it.
Checks to try
  • Water inlet hose and supply pressure checked and reported as good
  • Inlet filter at the back of the machine removed and cleaned
  • Confirmed only cold water hose attached
  • Confirmed water added through the drawer filled the machine, so it was not immediately draining away
  • Compared expected dispenser flow with a diagnostic video and found actual flow only trickled
Parts or tools mentioned
  • Inlet filter
  • Black rubber pressure-reducing insert
  • Water inlet valve

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

The black rubber behind the filter is to reduce the pressure down and should be there. It's fitted to cold water valves, some of which have high water pressure that needs taming. I have in the past removed it in cases where the water pressure supply was very poor and it helped to increase the water flow a little but if you have normal water pressure it shouldn't need removing and isn't related to your fault if the washer has worked ok before.

If the washing machine is otherwise working ok there may well be nothing wrong. If not enough water gets into the machine it should fail to work or abort with an error code. Many modern washing machines hardly use any water at all during the wash cycle and it's normal to hardly see any.

Thanks for the reply.

I've seen a video online of the washing machine going through the diagnostic tests, and the water that fill the tray comes out at a good speed. In my washing machine the water doesn't come out ... very much at all. Trickles. I'm unsure if the machine senses that "enough" water comes through, and it certainly does not take in the suggested amount in the manual for the specific programs, I'm certain.

Oh well, at least I know what the rubber thing is for. Perhaps time for a new machine.

If the water isn't going into the soap drawer at a reasonable flow rate but the water supply is ok and there's no hose kinking when you push the machine back plus the water filter is clean then I'd have to suspect a problem with the water valve. They normally either work or not but it could be caked with limescale or something inside.
