Chaps, your input would be gratefully received.
I will keep it short. Anna had a new rotary pump just before Christmas. I fear the pump failure was symptomatic of something else.
Her boiler pressure is set with the range 0.7-0.9 Bar. She brews fine. Water appears at the head instantly though there is a slight grumble from the pump that could either be a rattling spindle (the new pump has a loose spindle between the pump and motor whist the old one was fixed in the pump) or I fear a momentary dry running of the pump whilst it primes.
She is also losing boiler pressure whilst steaming. She used to stay in the 0.7-0.9 Bar range and steam all day. She now drops quickly to 0.5 Bar and struggles. Her recovery is also rather abrupt. We can't see any leaks and now wonder about the heating element and maybe scale on it though we doubt the latter.
The solenoid, anti-vac and fill probe have all been removed, cleaned and appear fine, though there anti-vac did appear to be leaking steam a little prior to cleaning. Anna has been descaled. The wand and tap nuts are tight.
Any thoughts please?
