Junkers WRD11 Automatic Heater Membrane
Junkers automatic water heater diaphragm.
This diaphragm has the letter E printed on the top of the metal plunger.
However, if your water heater is listed below as a compatible model, this diaphragm is the correct one for your heater.
Your original diaphragm may have been yellow. Junkers replaced all yellow diaphragms with these much more durable, transparent silicone ones some time ago.
If your diaphragm is torn or damaged, your Junkers heater may not ignite, spark, or heat up sufficiently.

Impeccable service
Enrique Manuel Romero Santos –
I placed this membrane on my Junkers ZW20-1KE23 heater and it started working normally again
