We have an automatic sensor that controls the operation of the Whale shower pump . Bavaria C37 (2015). It has failed. Trawling the Whale website there is a sensor located in the tray water inlet. A Whale drain plug with IC automatic sensor or Whale Gully IC. Replacement drain is Part No. 19760 model 408424 BH.
Anyone had a similar early failure, is it worth buying replacement £90 +. Perhaps there is a work around to connect a switch directly to terminals, any thoughts to share would be welcome.
