There are two main faults with combi boilers not giving hot water. one is a faulty flow sensor, the other is the most common which is a blocked heat exchanger caused by debris and scale in the system. this needs to be flushed out or may require a new heat exchanger depending on the age and condition of the boiler some plumbers may suggest a new boiler.

Why does it take two bowls of water before water gets hot on combi boiler


The water isn't maintained hot (unless the central heating is on) in a combi boiler. you will, therefore have to turn the water on, which activates the burner. The burner will then have to heat up the heat-exchanger which then supplies the hot water through cold pipes. Once the pipes are warm, you will receive hot water.

Heating pressure gauge goes up


yes tami
there should be a pressure rellief valve fitted.

Very Hot water coming out of overflow pipe


Is your boiler heating your domestic hot water if so i would turn water off to water maker and see if your boiler pressure stays down below 20 psi. If so water maker is bad. The other thing that could cause this problem would be the boiler pump is out.
