Pump display shows E19 and the unit restarts repeatedly without user input

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

Unstable mains supply causing frequent brownouts, Loose power terminals in DAB control box, Faulty internal power supply on control module

Safety first: Isolate power before tightening terminals.

Steps to check:

Inspect power connections: Tighten all line and neutral terminals in the DAB control box and at the breaker.
Check for shared circuits: Avoid running the pump on a circuit with heavy loads (e.g. large motors) that cause voltage dips.
Monitor voltage: Have an electrician log the supply voltage during operation.
If supply is stable but E19 persists: The internal power supply section of the DAB control module may be failing and should be replaced.
