over heating
The things to check firstare:
1 That the main valve cominginto your house is fully open.
2 Then check that the valve on the line to the heater isfully open.
If these valvesare not fully open then there may not be enough water getting to your heater.Check any filters are not blocked.
The other possibility is a faultytemp control valve not allowing the correct amount of water into the shower.
