My wife mentioned this a while back just after the BG person did a service, but I couldn't reproduce it myself until the other day.
She said that the shower temperature was repeatedly going from hot to cold - so cold she has to jump out. I ran the hot tap yesterday and it did the same thing, it would run at full temperature (so hot you can barely stand to keep your hand in) for 20-30s then cool down to just lukewarm over about 10s, stay there for ~20s then get back to hot. It did this several times with the whole cycle being perhaps a minute.
What might be the cause of this, I didn't want to call out a plumber in case they cannot repeat it and charge me a call-out fee as it doesn't seem to always happen? Could it be some setting the engineer changed or is that just a coincidence it happened right after they were here?
The boiler is a Baxi combi, about 2-3 years old and it passed the service without any reported issues (and the one the year before).
Any help appreciated, obviously it's not a great time of year for cold showers
