5.15 Circulation pump (if featured)
5.15.1 General characteristics
Jetsystem models are fitted with a synchronous circulation
pump which continuously circulates the water from the filter
body into the tub through the bellows seal.
5.15.2 Electrical symbol
5.15.3 Checking for efficiency
NO RE-CIRCULATION - POOR WASHING RESULTS
1. Check that the impeller is not jammed and check for slippage.
2. Check the resistance of the stator winding, which should be approximately 150/200 Ω.
Important!
If caused to run empty (i.e. disconnected from the hydraulic circuit), synchronous pumps may fail to start up.
This is because, due to their structural characteristics, they require a counter-torque on the impeller to allow
the rotor to turn in one direction or the other.
For this reason, the pumps should be tested only when fitted to the appliance and after introducing a certain
quantity of water.
