Heating

Repairs

Repair work on the machine should only be

done by specially trained personnel.

Replacing the heating elements

Wen replacing the heating elements, there

is a risk that water still left in the machine

may flood onto the floor. Be sure to dry up

any spilled water since it may cause people

to slip and hurt themselves.

1. Take down power from the machine.

2. Remove the front cover.

3. Make a note of how the heating elements are

connected.

4. Disconnect the connection to the heating

element to be replaced.

5. Unscrew the nut between the connections

approx. 1 cm.

6. Push on the nut and bolt to undo the expan-

sion bracket from the outer drum.

7. Remove the old heating element and install

the new one. Be sure that the rear edge is
fitted into the element holder at the rear of the
outer drum.

8. Assemble in reverse order.
