5. MAINTENANCE AND ADJUSTMENTS

WARNING!
!
ALWAYS FOLLOW SAFETY INSTRUCTIONS! DO NOT BYPASS ANY SAFETY DEVICES OR THEIR
PARTS. ANY INTERFERENCE TO THE MACHINE FUNCTIONS AND CONSTRUCTION ARE PROHIBITED!
USE THE PROPER CHEMICAL AGENTS WHICH AVOID CALCIUM SEDIMENTS ON HEATING ELEMENTS
AND OTHER MACHINE PARTS. DISCUSS THIS ISSUE WITH YOUR SUPPLIER OF WASHING PRODUCTS.
THE MANUFACTURER OF THE MACHINE IS NOT RESPONSIBLE FOR THE DAMAGE OF HEATING
ELEMENTS AND OTHER MACHINE PARTS DUE TO CALCIUM SEDIMENTS.
DO NOT OPERATE THE MACHINE WITH BROKEN / MISSING PARTS OR OPENED COVERS!
BEFORE MAINTENANCE WORK DISCONNECT THE MACHINE POWER SUPPLY!
WHEN THE MAIN SWITCH IS TURNED OFF THE INLET TERMINALS OF THE MACHINE MAIN SWITCH
ARE STILL UNDER CURRENT!
THAT IS THE WAY TO AVOID INJURIES.
In case of serious failures call the technical service of your supplier.

5.1. MAINTENANCE

DAILY CHECKING AND MAINTENANCE
1. Check that no linen or other parts (paperclips...) are left lying in the drum or in the rubber door seal, to
avoid damage to rubber or appearance of rust.
2. Clean the door seal from any remaining detergent and other foreign matter.
3. Clean the top and body when water or detergent traces are on the machine. Use a damped cloth, do not
use abrasive cleaners. Dry with a soft cloth.
4. The soap hopper should be cleaned at the end of each working day. Scrap sediments which may have
set inside the soap hopper with a plastic spatula and flush them with warm water.
5. At the end of the working day, open the machine door to allow airing out the machine.
6. At the end of the day it is recommended to shut off all main water and electrical supply. However, we don't
mean the individual faucets of the machines that may not be touched once adjusted, but only the main valves.
CHECKING AND MAINTENANCE EVERY SIX MONTHS
WARNING!
!
MACHINE PROTECTIVE CONNECTION AND EARTHING MUST BE CHECKED EVERY 6 MONTHS!
1. The filters in the water connection at the valves need to be cleaned. Turn off the tap. Unscrew the hoses
at the back of the appliance. Take out the filter at the centre with pointed pliers, clean and re-insert.
When re-attaching the hoses, make sure that the seals are seated correctly. Check water inlets for leaks.
Tighten the connections or replace the seals of the inlet hose if necessary.
2. On machines with electric heating check the tightening of the contacts of heating elements terminals and
other power terminals (main switch, fuse disconnectors, contactors).
3. Check :
– for the machine equipped with drain valve; that the drain valve is not leaking during the wash process
and that it opens properly afterwards (drain valve opens when electrical power falls off).
– for the machine equipped with drain pump; check that the pump gives its normal flow rate during
draining. The drain pump only needs to be cleaned if it has become blocked with foreign bodies (buttons,
paper clips...). Before this, any remaining water must be drained off.
WARNING!
!
HOT MACHINE PARTS SHOULD BE ALLOWED TO COOL FIRST!
First disconnect the appliance from the mains by taking off the plug. Remove the machine rear cover.
Drain off the last rest of water in the pump by opening plug (fig.5.1.,pos.1) of the small evacuation hose at
the pump and catch the water. Unscrew the pump side cover (2) and remove foreign objects. Clean the
housing and pump blades. Screw the pump cover back on again, close evacuation hose and mount the
rear panel back.
