Classeq Water Hammer / Inlet Valve Closure Shock

Classeq dishwasher shows water hammer or banging noises in the plumbing when filling.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Fast‑closing inlet valve, High water pressure, Lack of water hammer arrestor, Loose pipework

Safety first: Turn off water supply before modifying plumbing.

Check water pressure: Measure supply pressure. If excessively high, fit a pressure reducing valve to bring it within Classeq's recommended range.
Secure pipework: Ensure inlet pipes are clipped securely to walls to reduce movement.
Install water hammer arrestor: Fit a suitable water hammer arrestor near the machine's inlet to absorb shock.
Inspect inlet valve: If the valve is noisy or sticking, replace the water inlet valve.
