Washing Machine Wont Drain When Full But Will Drain And Spin When Most Of The Water Has Been Removed

Washing machine (Miele W 754 S) wont drain when full but will drain and spin when most of the water has been removed!

If the water is removed manually, it will then spin ok.

Also, once the pump is going I can recycle all the water that I've just removed from the drum, into the powder inlet and it will drain the lot)

Worked fine for years up until a few days ago.

I've checked:

- The pump is working.

- The filter is clear.

- Five tubes connected to filter:

-- Inflow to filter - Clear

-- Outflow, filter to base of drum - Clear

-- Outflow, small tube for emergency emptying - Clear

-- Outflow to drain hose - Clear

-- Inflow from side of drum (Is this an overflow?) - Clear

The filter did have coins and hair-grips in it which I removed. It was also stuck solid with limescale which I've de-limescaled. There was also lots of gunk that I've cleared.

I've also read through the tip: "washing machine not emptying the water" which was very useful.

Cheers

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.

Miele W 754 S drains only after water is manually removed

The problem
The washing machine would not drain when full of water, but if most of the water was removed manually it would then drain and spin normally. Once the pump had started, water poured back into the powder inlet would also drain away.
Likely cause
The strongest diagnosis in the discussion is a pump impeller fault: the pump may be jamming or failing to start under load due to debris wrapped around or interfering with the impeller, rather than a hose or filter blockage.
What fixed it
Recommended action was to inspect the pump impeller and pump chamber for obstructions such as a rubber band, hair band or other debris, and clear anything interfering with the impeller. One reply noted that access might require removing the pump housing to reach the motor and impeller. The exact repair carried out was not confirmed by the original poster.
Checks to try
  • Pump reported as working
  • Filter checked and cleared of coins, hair grips, limescale and gunk
  • Inflow to filter checked clear
  • Outflow from filter to base of drum checked clear
  • Emergency emptying tube checked clear
  • Outflow to drain hose checked clear
  • Inflow from side of drum checked clear

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

The pump could be jamming or not starting up. If once running it pumps out ok it implies the fault isn't caused by blockages. I would check the impeller doesn't have something wrapped round it like a rubber band or one of those elastic things females have in their hair. Possibly something else could be inside the pump chamber interfering with the impeller.

Hi I agree Andy the impeller could be obstructed by a hair band seen this fault before but with a samsung.I had to remove the pump housing to get to the motor and the impeller.
