Baxi boiler showing E50 in Brownhills? It usually points at the hot water sensor. What it means and what happens next.
E50 on a Baxi combi usually points at the hot water sensor. That sensor reads the temperature of the water going to your taps. When it fails, the boiler cannot control the hot water and shows the code.
The cause is usually the sensor or its lead. On some models scale in the hot water side affects the reading. Your manual will confirm the meaning for your model.
Some Brownhills streets have fairly hard water, and scale builds up inside combis over the years. Hot water that runs hot and cold before the code appears is a typical sign.
Switch off, wait a minute, switch on and reset once.
Mention if the hot water has been running hot and cold lately. It helps the engineer narrow it down.
Tell us if the radiators still warm up. On many models only the hot water is affected.
Tests the hot water sensor and its connection, checks for scale, and replaces what has failed.

If the heating still works, you can keep warm while the part is arranged. Boil a kettle for washing up and avoid resetting the boiler again and again. It will not bring the hot water back.
No. It is a sensor fault on the hot water side. Any smell of gas means leaving the house first, leaving switches alone, then calling 0800 111 999 for the National Gas Emergency Service.
It can play a part. A scale reducer on the mains can help protect the boiler afterwards.
Often on the first visit, once the sensor is on hand.
