Hi,

We have a Bosch WDU28560GB washer/dryer and I noticed that it wasn't drying very well and what I assume to be the fan constantly runs for hours post drying cycle.

The same thing happens if on a hot wash, there sounds like there is a motor running. But the door opens.

It doesn't happen on a 15/20 min 40 degrees wash.

Any ideas what the issue could be?

I did the usual of checking for blockages in the drainage pipe etc. no issue there.

Bosch WDU28560GB runs on after cycle and dries poorly

The problem
Bosch WDU28560GB washer/dryer was reported to dry poorly and to have a fan or motor-like noise running for hours after a drying cycle. A similar motor noise was also heard on hot washes, although the door could still be opened. The issue did not occur on a 15/20 minute 40 degree wash. The drainage pipe was checked and no blockage was found.
Likely cause
The accepted reply suggested the noise could be the water pump in the base running because a leak has been detected. This was presented as a possibility rather than a confirmed fault. If the noise is definitely the dryer motor, the exact cause was not identified in the discussion.
What fixed it
No confirmed repair was documented. The strongest supported diagnosis is that the base pump may be running due to leak detection. Further diagnosis should be carried out by a suitably qualified appliance engineer.
Checks to try
  • Drainage pipe checked for blockages; none found
  • Issue occurs after drying cycle and on hot wash
  • Issue does not occur on a 15/20 minute 40 degree wash

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

That could be the water pump in the base. If it runs after cycle finished it can indicate a leak is detected. If it is definitely the dryer motor though I'm not so sure why that would be.
