I have a Mira Elite QT. Its been installed about a month now. My problem is after a few minutes of the shower running normal it goes scalding hot out of the blue. It then goes freezing, hot, freezing hot & so on. The only way to get back to normal is to turn it all the way to cold for 30 seconds & then put it to regular showering setting.
Without touching the dial the whole thing repeats itself a few minutes later.
Any tips on this??
