Hi
My La Cimbali Junior (i.e. water tank version) is around 10 years old and the Ulka EX5 pump is making a loud noise when water is run through or when making a shot, but it quiets down when pressure builds up during backflushing of the machine. It's still pumping water through and making coffee but the noise is getting louder. I have pushed water through the machine under pressure with a syringe to make sure there's no air trapped in the pump but it didn't make any difference.
I have a new Ulka EX5 pump and rubber mounts and am wondering if it is a fairly simple job to replace the pump that I could do myself. If so, I would appreciate some advice on the steps,
Also, I have a Ranchio Silvia which I have descaled using citric acid in the water tank and flushing through and letting it sit inside the machine for 20 minutes and repeating this process a couple of time and then running a few litres of fresh water through the machine to clean the citric acid out. My question is,can I descale my La Cimbali Junior using the same descaling process with citric acid in the water tank. Again, some advice on the steps to undertake this would be appreciated.
Thanks for your assistance,
Graham
