Buzzing

Hi,



Have just replaced the TCO for about the 4th time in a couple of years - seems to fail repeatedly and there is quite a bit of corrosion/verdigris on top of the heater tank. This time, I replaced the TCO and cleaned away the corrosion deposits underneath the TCO and the shower initially ran fine. However, after a couple of minutes running on high, a buzzing sound starts, which gets louder, and the water seems to cool down (but not go completely cold - just not as hot as when first turned on). Any ideas what this might be? I've checked the heater elements with a DMM - both about 11 ohms.



(BTW, this shower also exhibits the 'wailing noise' others on here have mentioned, when the heat control/flow valve is set to about the desired temperature, goes away when turned up or down etc. Not sure if this could be related; I've always assumed it wasn't really a problem and just one of those things.)



Thanks in advance.

The buzzing sound maybe that the TCO connections are loose or that the heating can is about to fail.

There should be about 2-3 ohms difference between elements.
