LaPavoni boiler cleaning

[mrldcty]

My LaPavoni Bar S3 has developed a problem with the quality of water in the boiler. Both the steam and heated water provided by the supply valve emit a distinctive rust color and emit a rather rancid odor, especially noticeable when steaming.

The fresh water source is filtered and softened and has tested clear and clean.

I suspect either milk contamination or scaling as the source of the problem. Any other ideas as to the cause? Any suggestions for cleaning the boiler? :?

Citric Acid. 2.2lb bag will do 5 gallons of water. Look around for the little 7oz packets. That should clean up your Pavoni.

You may also want to drain your boiler tank and if possible, flush it out and delime it.

Another problem I have encountered is when someone leaves the steam wand soaking overnight in a glass of water. A siphon action can occur (especially if you turn the machine off at night) and the dirty water will be sucked up into the machine. You should Never leave a steam wand soaking in water.
