Gram Power Supply Instability / Clock Memory Loss

Oven clock resets to 00:00 after each power cycle or randomly during use.

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

Loose mains connection, Failing mains filter or power supply on PCB, Faulty clock/EEPROM chip, Voltage dips on household circuit

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

Steps to check:

Inspect and tighten all screws on the mains terminal block.
Check the household circuit for other heavy loads causing voltage dips; avoid sharing the oven circuit with large appliances.
If the issue persists, the control board may not be maintaining memory; replace the board.

Warning: Repeated power interruptions can also indicate wiring issues in the home; consult an electrician if in doubt.
