2 Days before christmas I notice my Giotto PP is running hot, well over 1.5bar pressure and plenty of steam.
On investigation I found that the preessurstat wasn't cutting out causing the element to keep heating the water.
Trying to find a suitable pressurestat in Brisbane was a bit of a challenge but I ended up getting a "Lefoo" branded one (part number 541020) from a local supplyer.
On installation and after heating up the Giotto was spewing steam from the connection to the p/stat so I removed it to inspect for the problem. Turns out the box had the wrong
part in it and I had a 1/8th" p/stat instead of a 1/4".
Next day (Christmas eve) I took it back to the Brisbane supplyer but he was unable to provide any other alternative.
I had to wait until the new year to order a Sirai from a sponsor. Anyway the new one arrives and on installaion turn on the machine and the power trips.
Double check the connections and all other electric wiring all looks good, try again same result - power fuse trips.
Just to be sure I havent received a faulty p/stat the old one goes back on, same result - power trips. So the new one goes back on.
If the power wires to the heating elememt are disconnected the machine turns on as normal and the pump operates to replenish the tank.
of course nothing more happens because there is no heating.
Plug the element cables back and it trips the power again.
Any thoughts on the possible fault?
Could the steam escaping from the pressurestat connection done damage elsewhare?
Cheers
Steve
