Zanussi ZWF1221W detergent drawer not flushing main wash powder

The problem

On a Zanussi ZWF1221W washing machine, the main wash section of the detergent drawer was no longer being properly flushed through. A solidified amount of powder was being left at the front of the drawer. The user had already checked the water holes above the drawer and reported no obvious blockage, and said the household water pressure had not been altered.

Likely cause

Reduced water flow into the drawer was the most strongly supported diagnosis. The accepted reply suggested the inlet valve filter may be partially blocked. Damp detergent or unsuitable tablets causing clogging were also mentioned as possibilities, but these were not confirmed.

What fixed it

Check for reduced fill flow, particularly the inlet valve filter for partial blockage. Also ensure detergent is dry and, if using tablets, that they are the type intended for use in the drawer. No confirmed repair was posted, only diagnostic advice and a possible workaround of using suitable tablets placed with the laundry.

Checks to try

• User checked the water holes above the drawer and found no obvious blockage
• Accepted reply advised checking for reduced water flow
• Accepted reply specifically mentioned checking the inlet valve filter for partial blockage
• Accepted reply suggested checking whether detergent was damp or tablets unsuitable for drawer use
