Smell From Washing Machine

Hi, I am new to this forum and this is my first post.

I am just finishing refitting my daughters kitchen, which included adding a trap for the washing machine outlet. I did this because previously the outlet went out through the wall to an open drain (it's and older type house) and she was getting a drain smell when the machine was used. I assumed it was coming back up the waste pipe, hence the new trap. After the first wash I noticed the smell was still there, so now I am thinking it is the machine itself, or maybe the end of the outlet hose that goes into the stand pipe. I would be grateful for advice please, also, where do I get one of those hook things that helps the hose to hang in the stand pipe.

Cheers

Malcolm

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.

Washing machine smell remained after fitting waste trap

The problem
A drain smell was noticed when the washing machine was used. The discharge had previously gone to an open drain, so a new trap was fitted, but the smell was still present after the first wash.
Likely cause
The strongest supported diagnosis is that the smell was likely from contamination inside the washing machine rather than only from the waste pipe. The accepted reply said the machine can retain water in the sump hose, and that the appliance may need several maintenance washes to clean it. Other forum replies suggested possible drain issues, but this was not confirmed.
What fixed it
Recommended action was to carry out several maintenance washes to clean the machine. No exact repair or replaced part was confirmed in the discussion.
Checks to try
  • A new trap was added to the washing machine outlet
  • The smell was still present after the first wash after fitting the trap
  • Accepted advice noted that the washing machine sump hose normally retains some water

Safety: Disconnect the appliance from the electricity supply before any inspection. Work involving mains electrics, gas or sealed refrigeration systems should only be carried out by a suitably qualified appliance engineer.

Hello Malcolm and welcome. You are right, a washing machine pumping out into an open drain is bad, and can allow drain smells up through into the Kitchen. It shouldn't normally get into the washing machine so much because it has its own water trap in that the sump hose is always full of water. This isn't by design, it's just that the pump can never pump all the water out and tends to leave a pint or so in the sump hose.

It may be that the washing machine needs several maintenance washes to clean it. Read this topic for further advice

Yes, it's actually the machine that causes the smell. One possible cause of this is the water collected under the rubber door seal of your machine. If it is not drained over the time, it creates a bad odor.

If your washing machine smells so much from inside, it is probably has mold and mildew. Mold and mildew can grow quickly in the washing machines, that are installed in damp environments and those that are not aired properly after use.so those are the most common reason for smelling from washing machine.
