Miele washing machine shows 'check drain' and will not complete cycle

The problem

A Miele washing machine was not draining properly, the 'check drain' LED was flashing, and the wash cycle would not complete. The user had already found and removed two hair pins and a 5p coin from the drain filter area. The under-sink trap was reported clear, the machine could drain from the drain filter access panel, and the pump impeller was spinning but sounded 'crackly'.

Likely cause

Most strongly supported diagnosis was a blockage in the drain hose or at the U-bend connection where the drain hose fits. The accepted reply also noted that the observed noise may simply have been the impeller hitting water, and that the pump is unlikely to work normally with the filter removed.

What fixed it

The accepted advice was that if the pump is running, the impeller is not loose on the shaft, and the impeller blades are intact, the machine should pump water through the drain hose. If it does not, the likely issue is a blockage further along the drain path, particularly the drain hose or U-bend connection. The exact repair carried out was not confirmed in the thread.

Checks to try

• Under-sink trap checked and reported clear
• Machine was able to drain from the drain filter access panel
• Hair pins and a 5p coin were removed from the drain filter area
• Pump impeller was observed spinning
• Accepted advice to confirm the impeller was not loose on the shaft and that the blades were not broken
