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

Faulty mode selector switch, Damaged control PCB, Broken mode button contacts, Firmware glitch

Safety first: Remove the battery before opening the handle or control panel.

Power reset: Remove the battery for 1–2 minutes, then reinstall and test mode changes.
Check buttons: Press each mode button firmly. If one feels stuck or does not click, clean around it and inspect internally.
Inspect PCB: Open the control area and check for cracked solder joints or damaged traces around the mode buttons.
Replace control PCB: If the buttons are mechanically sound but modes still do not change, replace the main control PCB.
