I have the above shower and its worked perfectly well until now. The shut off button works but then the shower will spontaneously restart for short periods unless isolated by main electrical pull switch to switch off completely. The low pressure button does NOT come on but the shower heat button ( l or ll ) will spontaneously go off during your shower as well making it very uncomfortable. I rang someone today and he said it would cost 60 quid for the front casing/board plus 60 to fit. Am i better to replace the whole shower? please help me ASAP
