Hi Don, does the black grid look choked at all.?
If so, just get an old tooth brush and clean the grid.If it is not, you will have to change the pressure switch.It is easy but you have to be VERY careful,the base and top will slice into your flesh.Cover all sharp edges well.Take the front silver cover off at the base and look behind the hose to the heater.Pull off the white plastic wiring plug.Get your fingers around the p switch and feel to the right.there is a holding clip.Gently move this outwards and then turn the whole switch anti clockwise half a turn then pull gently.the press switch then comes away.reverse to fit the new one.All the best.
