Why is there No hot water coming from taps and no pressure in combi boiler?

If there is no hot water coming from the taps and no pressure in a combi boiler, it could be due to several issues. A common reason is low water pressure, which may be caused by a leak in the system or a faulty pressure relief valve. Additionally, the boiler could be in lockout mode due to overheating or a fault, preventing it from heating water. Checking the pressure gauge and ensuring it’s within the recommended range, along with inspecting for leaks, can help diagnose the problem.
