I have a 9Kw electric shower for 2 years without any problem until this morning. The cold water pressure and flow rate is very low with the power off. When the electric power was turned on, the shower release boiling hot water with very low flow rate regardless the postion of temperature control. Even removing the shower head won' t solve the problem. I have no pressure problem with tap water in the same bathroom. Is this a prolem with the electric shower or supply water to the shower?
Thanks
