Fixed!! With a happy ending! And a minor flood ![Face with rolling eyes :rolling_eyes: 🙄](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f644.png)
I opened up the o ring box before starting and found an open packet of bosch ones i bought for the last replacement... and there was another 8 left!
I followed the instructions and had it apart in minutes, the longest process being drain down.
I soak the exchanger with vinegar. After 45 minutes i tipped it out and washed it through, got some dark water and a few small fragments. I wasnt sure it was empty of crud so i made up some citric acid and did that for 30 mins, flushed and decided to do it again ( its only time )
At this point i took a cup of tea and some apple crumble into the lounge and we watched hollingbury drive![Rolling on the floor laughing :rofl: 🤣](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f923.png)
When i went back into the kitchen, tyere was quite a bit of water on the worktop.... and floor! One on the valves i shut off must have been slowly letting water past, it slowly filled the boiler until it started coming out of the open heat exchanger holes![Unamused face :unamused: 😒](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f612.png)
Anyway, 5 minutes and I had it back together, purged the hot tap then turned boiler on while i cleaned up the water. It got up to late 70s then cut out and when the reading dropped to 65 it cut back in, so we now have hot running water again![Grinning face with big eyes :smiley: 😃](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f603.png)
If the rads heat up again I'll get a diverter valve, but for a minute, I'll call this a success!
Thank you for your input everyone![Thumbs up :thumbsup: 👍](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f44d.png)
