Grundig Trigger Switch / Control Fault

Vacuum does not respond to trigger-style on/off control (for models with trigger).

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

Broken trigger lever, Worn microswitch under trigger, Disconnected trigger wiring, Stuck trigger due to dirt

Safety first: Remove the battery pack before working near the trigger.

1. Inspect trigger movement: Ensure the trigger moves freely and returns when released. Clean around it with a dry brush.
2. Check for mechanical breakage: If the trigger feels loose or does not spring back, the lever or spring may be broken and the handle assembly must be replaced.
3. Electrical fault: If the trigger feels normal but the vacuum does not start, the internal microswitch or wiring is likely faulty and requires handle disassembly by a technician.
