temp fluctuation
The things to check first are.
1 That the main valve coming into your house is fully open.
2 Then check that the valve on the line to the shower is fully open.
If these valves are not fully open then there may not be enough water
getting to your shower to cool it properly, the overheat safety devicewill turn
the power off until it cools, then it then it starts to heat again andso on.
Make sure that the shower head is clean and clear,that the hose isn’t kinked (this can happen just behind the hand set where itis difficult to see) also check the inside of the hose although it can look OKon the outside it could have collapsed internally
The other possibility is a faulty flow valve notallowing the correct amount of water into the shower.
