vaillant turbomax plus 824e boiler

[tonyam]

hi
has anybody got any idea of the problem with my boiler.runs fine for the heating but hot water flutuates in and out. withe the hot tap left running the boiler cuts in and out, and there has been a noticable drop in pressure since the problem accured.
Thanks

do you mean hotwater pressure or the pressure dial on the front?

Id check dhw thermistor

if your cold water has the same flow rate check the filter on the boiler
