Arktic Circulation Pump Failure

Water is not circulating over the evaporator plate; reservoir full but no water flow

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

Failed circulation pump motor, Blocked pump inlet, Airlock in pump, Loose wiring to pump

Safety First: Unplug the unit before working with water components.

Steps:

Inspect reservoir: Ensure the water level is adequate for the pump to prime.
Check pump inlet: Remove debris or scale from the pump intake screen.
Test pump: With power applied (only if qualified), check for voltage at the pump. If voltage is present but the pump does not run, replace the circulation pump.
Bleed air: After replacement, ensure the pump is fully submerged and run briefly to remove airlocks.
