Primus Water Level Sensing / Siphoning Issue

Washer fills and drains repeatedly without progressing into the wash phase.

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

Drain hose installed too low causing siphoning, Blocked or kinked pressure hose, Faulty pressure sensor, Control misinterpreting level

Safety first: Unplug the washer before adjusting hoses or opening panels.

Correct drain hose height: Ensure the drain hose is at the recommended height and not inserted too far into the standpipe.
Inspect pressure hose: Check the small hose from tub to pressure sensor for kinks or blockages and clear as needed.
Replace pressure sensor: If hose and installation are correct but behavior persists, replace the water level pressure sensor.
