Worcester Bosch combi boiler making strange noises and no heating no hot water fault

Here’s a step by step guide to a combi boiler breakdown I went to today that turned out to be a simple fix without needing any parts to get it back up and running

That was properly clogged up. How do these service companies keep their customers

3hrs 🤔 Surely decent wash through with a gentle cleaner. Maybe bicarbonate soda.
Happen to me. Horrible traps.

I watched just for the “ happy days”😂

Thank you I had the same problem and watched another RUclips video explaining the same as you have and works fine. Although some time in the future I will replace the PRV as it leaks when temperature is turned up. Advance Happy New Year 2024. Keep up the good work dear friend.🎉👋

Super helpful vid . Fixed my boiler today , it was working but making a bubbling noise and no vapour outside. Took cover off located condensate. Full of muck . Took out and cleaned put back working fine .
