Ash screw jammed
If the ash screw is stuck, a corresponding warning will
be displayed on the screen.
The most common cause of a blockage is a full
ash bin. So first check to see how full the ash bins
are and empty them. If the ash bin is not full, then it can
be assumed that a foreign object is blocking the ash
screw.
1. End the boiler's heating mode with the On/Off
switch in the boiler overview window. As
soon as the [Switched off] operating condition is
displayed, switch off the boiler with the mains
switch.
2. Detach the ash bins from the boiler and check the
visible part of the ash screw. The foreign body may
already be found at the end of the ash screw,
where it can be removed.

3. If no foreign body is visible, it is probably in the
combustion chamber under the tilting grate.
Remove both combustion chamber covers from
the combustion chamber.
4. The grate cannot be tilted by hand. Tipping is done
by starting de-ashing with the [De-ash] button.
The grate tilts and remains in this position for ap-
proximately 15 seconds.
WARNING!
Danger of crushing due to tilting grate

When the grate is tilted, switch off the boiler with
the mains switch. This causes the grate to remain
in this position so injuries are prevented.
Now the ash screw under the tilting grate is
accessible and the foreign body can be removed.
5. After removing the foreign object, replace the
combustion chamber covers and reattach the ash
bins to the boiler.
6. Switch on the boiler with the mains switch. To
check, start de-ashing by pressing [De-ash] .
If no error message appears, switch the boiler back on
with the On/Off
switch. If there is still a
blockage, the ash screw must be removed.
Removing the ash screw
If the ash screw is jammed or the foreign body
cannot be removed, the ash screw must be
removed.
