The Harris pump intermittently stops with E13; the display may flicker.

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

Failing low-voltage power supply on the control PCB, Loose internal connectors, Voltage spikes from the line, Aging electrolytic capacitors

Safety first: Disconnect power and wait several minutes for capacitors to discharge before opening the control housing.

Inspect internal connectors: Gently press on all plug-in connectors on the control PCB to ensure they are fully seated.
Look for bulged capacitors: Examine the control board for swollen or leaking capacitors, burn marks, or discoloration. These are signs of a failing power supply.
Check for overheating: Ensure the control housing is not exposed to direct sun without adequate ventilation, which can accelerate component failure.

Internal power supply faults generally require replacement of the Harris control PCB or the complete control module.
