Subject: Dead Oscar...pump need to be replaced?
 

Oscar brew head spray had been weird for a couple months, very active dispensing like a wide shower rather than a thin stream. Cooling flushes did nothing to diminish this; feared was overheating/building up too much pressure as always left on, but when flushed out all water, turned off and cooled down and replaced water, same shower action happened. Still brewed a decent shot, but something amiss.

Now, it appears dead. Get some pressure from steam wand, but when try to pull a shot get a faint hum and then silence, and no brew pressure.
have turned off for hours, tried again after giving time to heat up, but no luck.

Will the fix be as simple as replacing boiler and pstat, or potentially a more major problem?

thanks in advance

Well, it could be the pump, they often need replacing in 3-5 years.  And for $50 with free shipping from Chriscoffee or espressoparts I could have one on order no matter what.  Sooner or later you will need it.


What is your water like?  
When was the last time you descaled?
How often do you clean your shower screen?
Any weird sounds or leaks?
