Gaggenau Power supply instability to control electronics

Oven clock and timer reset themselves or lose time frequently

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

Intermittent mains supply, Loose mains terminal block, Failing control board power supply, Electrical noise on supply line

Safety: Turn off power before accessing the rear terminal block.

Check mains stability: Verify that other appliances on the same circuit are not causing voltage drops (e.g. large motors starting).
Inspect terminal block: Tighten all screws on the oven's mains terminal block and check for heat damage.
Dedicated circuit: If possible, connect the oven to a dedicated circuit as recommended by Gaggenau.

Note: If the issue persists despite a stable supply, the control board's power supply section may be failing and require replacement.
