This 2000W heating element, BSH part 644726, is a genuine replacement for Bosch, Siemens and Neff appliances. The same part is also listed as 00644726. It's the factory heater, rated to match the original load so the controls and safety cut-outs work as designed. The appliance type and models aren't on file, so match the number stamped on your old element, or send us the E-Nr from the rating plate before ordering.

How to tell a 2000W element has failed

A heating element is a resistance wire sealed inside a metal sheath or mounted in a frame. Current through the wire makes heat, which the appliance's controls switch on and off as needed. Elements usually fail by going open circuit, so the appliance runs but never warms up, or by shorting to the sheath, which trips the safety switch the moment heat is called for. Visible splits, blisters or burnt terminals are a giveaway. A multimeter test across the terminals with the power isolated confirms it.

Replacing the heating element

Isolate the appliance at the switchboard or unplug it, and turn off the water if it's connected. Photograph the wiring before you undo any terminal. If the element mounts through a seal, fit a new one so it doesn't leak. Tighten terminals firmly so they can't overheat. Hard-wired appliances must be reconnected by a licensed electrician. Test the appliance through a full heating cycle.

Questions about this part

How do I test the old element?

With the power isolated and the wires off, check across the terminals with a multimeter. A healthy element shows a low resistance, typically a few tens of ohms. An open circuit, or any continuity from a terminal to the metal body, means the element has failed.
