Miele W961 Filter Empty Faucet from Hose Filter Keeps running after cleaning the filter, when filling the machine

I cleaned the filter on my perfectly running (up to now) old Miele and when I started a normal, short cleaning cycle, the faucet on the hose behind the cleaning filter door on lower left side of the machine kept running as fast as the water entering the machine. I re-opened and resealed the filter, but same problem continues. I read all trouble shooting notes here, but nothing about this type of leak from the filter drain hose. Please help, I really appreciate this machine.

Miele W961 leaking from emergency drain hose after filter cleaning

The problem
After cleaning the pump filter on a Miele W961, water entered the machine normally but then ran out continuously from the small emergency drain hose behind the lower-left filter flap. The hose itself was reported as undamaged and no other lower hoses or fittings were leaking.
Likely cause
Most likely the emergency drain hose is missing its bung/stopper, or it is not sealing correctly. The discussion indicates this hose should be sealed at the end, and water was escaping through the open outlet rather than from a split hose.
What fixed it
The recommended action was to check for the missing bung/stopper for the emergency drain hose, including whether it had fallen inside the base or under the machine, and ensure the hose end is properly sealed. The original poster temporarily stopped the leak by fitting a tight plastic cap/cork into the open end, but this was only described as a temporary workaround. The exact proper repair was not confirmed.
Checks to try
  • Confirmed water was coming from the emergency drain hose behind the filter flap
  • Confirmed the hose was not split or damaged
  • Confirmed no water was leaking from any other hose or fitting in the lower part of the machine
  • Re-opened and resealed the filter, but the problem remained
  • Temporary sealing of the hose end with a plastic cap/cork stopped the leak
Parts or tools mentioned
  • bung/stopper for the emergency drain hose
  • temporary plastic cap/cork

Hi. Sorry I'm not fully following the faucet bit. I know it's an American word for tap but I'm confused because there isn't a tap behind the pump filter door. Do you mean the small emergency draining pipe that normally has a sort of bung in the end?

Miele W961 Filter Hose Run

Hi Andy, yes, it is the emergency pipe that has a kind of a T shape, with one open and one closed orifice at both ends of the small segment of the “T”. The larger orifice points down and is attached to a plastic clamp that holds it from twisting upwards when draining. Thanks

OK, so water is running out of this hose? It should have a bung in the end, or maybe push-fits onto something that acts as a bung. Where is the water coming from, is it leaking from the pipe itself as in it's damaged or split? Or is water getting past the bung or not sealing when pushed onto the holding place?

Miele W961 Filter Hose Run
Answered about 7 years ago

Yes, water is running out of this hose, the hose is not split, nor water comes out from any other hose/fitting in the lower part of the washing machine for that matter. The hose is attached to the filter housing area, so water comes into the filter and continues to run out through this hose. There is no pressure on the hose (if I just closed the orifice with my finger, FYI). AS mentioned above,this problem started right after I cleaned out the filter and screwed back the access lid.

Currently, I found a perfectly fitting plastic cap/cork, about 8 mm in diameter, that fits very tightly inside the open end of the T shaped plastic piece attached to the hose, and effectively seals the opening. It seems to have solved the leaking problem, temporarily, at zero cost, but the next time I clean the filter out, I may have a hard time pulling the cork out and/or, will have a large quantity of water coming out from the filter lid when I unscrew it to clean it out.

To clarify, the T shape end of the hose is not a functional BUNG per say (like a stopper, let's say, used on wine caskets). This plastic T shape end has an orifice that is not plugged, nor can it be pushed in or fitted into a device/bracket/etc that would cause it to be plugged and therefore play the role of a "bung". As I mentioned, one of the short end of the T is open, one end is shut by design and one end is fitted onto the hose itself.

Hope this helps, and thanks for your time in helping out.

Hello. The end of the hose has to have a bung fitted or must fit to a stopper. It’s strange because you wouldn’t expect the bing to be so loose fitting it could become dislodged accidentally just cleaning the filter. If there should be some sort of bung it must be somewhere. Maybe it fell inside the base or under the washer somewhere.
