Hotpoint WD440 ejecting water from dispenser due to restricted draining

The problem

A Hotpoint WD440 was throwing water out of the dispenser drawer, mainly during rinse/spin, and sometimes stopping with water left in the drum until power was cycled. The drain hose and household waste pipe had already been checked and were reported clear.

Likely cause

Confirmed partial blockage in the drain path, specifically debris trapped under the ball valve area in the sump hose, slowing water evacuation enough for water to back up and exit via the dispenser drawer.

What fixed it

Check and clear the pump filter or, on this machine type, the hidden filter area in the sump hose. The blockage was removed from under the ball valve area and the machine then completed rinse/spin and a full wash normally.

Checks to try

• Drain pipework checked and reported not blocked
• Drain hose checked and reported OK
• Pump/filter area inspected
• Debris found under the ball valve ('ping-pong ball thingy') in the sump hose
• Machine tested on rinse & spin and on a full wash after clearing blockage

Parts or tools mentioned

• Pump filter
• Sump hose
• Debris described as 'clothy' gunk
