5.1. MAINTENANCE
CHECKING AND MAINTENANCE DAILY
1. Remove the linen or other parts (paperclips, needles, …) who are left lying in the drum to avoid injuries
and damage to the rubber door seal, seals, glass etc.
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. Hoppers must be cleaned at the end of each working day. Remove sediments inside the reservoir by means
of a plastic spatula and splash by water.
5. Check water and possible steam inlets for leakage.
6. At the end of the working day, open the machine door to allow airing out the machine and to prolong the door
gasket life service. We recommend to shut off all electrical power inlets and main water inlets.
CHECKING AND MAINTENANCE EVERY THREE MONTHS
WARNING !
HOT MACHINE PARTS SHOULD BE ALLOWED TO COOL FIRST !
1. Check if the drain valve is not leaking during the wash process.It is also important that the valve opens
properly afterwards (drain valve opens when electrical power falls out).Wash out the drain if the water
doesn’t drain fluent.
2. Check for the belt tightness or possible damage; therefore remove the machine rear cover.
3. Check the tightness of the bolts according to chapter 5.2.
4. Check visually all hoses and connection inside the machine for leaking.
5. Make sure that the control components are protected against moisture and dust during the clean up.
Wipe and clean up the machine inside.
6. Tighten the contacts of heating elements terminals on machines with electrical heating.
CHECKING AND MAINTENANCE EVERY SIX 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 center 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.
BEFORE REMOVING TOP OR BACK PANEL OF THE MACHINE, SWITCH POWER OFF AND WAIT
FOR AT LEAST 10 MINUTES. BEFORE STARTING INSPECTION OF FREQUENCY INVERTER,
CHECK FOR RESIDUAL VOLTAGE ACROSS MAIN CIRCUIT TERMINALS + AND -. THIS VOLTAGE
MUST BE BELOW 30VDC BEFORE YOU CAN ACCESS THE INVERTER FOR INSPECTION.
2. Clean and remove dirt and dust from:
– the cooling fin of the inverter
– the motor cooling fins
– the internal ventilator of the inverter (if present)
