limescale remover or mechanically (take care, since the
elements are welded to the end panel).

• If there is leakage from the check valve, dismantle the check
valve and clean the sealing surfaces in the valve body and
on the O-ring. On re-assembly, the locking screw must be
screwed in until it bottoms in the valve body.
If the problem with the deposits is severe, we recommend
increasing the dosage amount (see “6.2 Checking the dosing
amount”).
