Replace the water unit membrane.*
At the appliance’s operation
increased noise of flowing water
is detected
Big water consumption.
Reduce water consumption.

consumption)
Reduce gas consumption or increase
water consumption.
Gaskets displacement in the water duct
joints.
Replace the gaskets.*
The main burner’s flame doesn’t
go out when the hot water tap is
closed.
