Display or indicator LEDs flicker or dim when 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 mains supply or extension lead, Failing internal power supply on PCB, Loose neutral or live connection, Motor drawing excessive current

Safety: Unplug the unit before inspecting internal wiring.

Check mains connection: Plug the Kobold carpet cleaner directly into a wall outlet, avoiding long or coiled extension leads.
Inspect plug and cord: Look for damage or overheating at the plug and along the cord.
Internal connections: Open the housing and tighten all screw terminals on the input and power supply sections.
Monitor behavior: If flickering persists and is accompanied by motor surging or unusual noise, the motor or power supply PCB may be failing and should be replaced.
