627648 Genuine Potentiometer for Bosch, Siemens, Neff Appliances, BSH 00627648 Control Potentiometer

Potentiometer 627648, also listed as 00627648, is a genuine part from the Bosch, Siemens and Neff range. A potentiometer is a variable resistor, usually turned by a knob, which the control board reads to know which setting you've chosen. The appliance this one belongs to isn't recorded with the number, so confirm 627648 on the parts list for your model before you order.

Symptoms of a worn potentiometer

As the control turns, a wiper slides along a resistive track inside the potentiometer, and the control board reads the changing resistance as a setting such as temperature, speed or program. Wear, dirt or moisture on the track gives the board patchy readings. You might see the display jump between settings, a knob that needs jiggling before the appliance responds, settings that change on their own, or one that can't be selected at all. Steam and grease near a control panel speed up this wear.

Replacing the potentiometer

Disconnect the appliance from power before opening the control panel, and use a licensed electrician if it's hard-wired. Pull off the knob, then note how the potentiometer is fixed and photograph its wiring or plug. Fit the new part in the same orientation so the knob positions line up with the panel markings. Test each setting once it's reassembled.
