My Worcester 2000 boiler is displaying a low pressure error message. Sometimes the hot water runs out (this was also happening also before the low pressure issue). I had an electrician come and check the electricity and he said all is good. The next day the hot water still wont work and he says i need to contact a "plumber". The light appears to be on and the water tank is full however, there is no hot water. There's an instant hot water shower that id not working.
