Aqmos Electrical Noise / Voltage Drop

Display shows random characters or resets when the drive motor starts

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

Weak power adapter, Loose power connections, Motor drawing excessive current, Faulty PCB power regulation

Safety: Use caution when measuring live voltages.

Check power adapter: Measure voltage under load and compare with rating. Replace if it sags significantly when the motor runs.
Inspect wiring: Ensure all power and motor connectors are tight and free of corrosion.
Test motor current: If possible, measure motor current draw. A motor drawing more than specified may be seizing and should be replaced.
Consider PCB repair: If power supply and motor are good, the PCB’s power regulation may be faulty and require board replacement.
