- Continuous Washing (Optional): An extended cycle where duration can be varied by pressing START (3) to interrupt wash and start rinse.
- Automatic Cycle Start-up: Enables the chosen cycle to start automatically when the door is closed. Activated by holding START (3) for five seconds with the door open.
- Emptying the Dishwasher:
- No Drain Pump: Switch off, remove integral filter (Fig.7A), pull up overflow pipe (Fig.8B), wait for tub to empty, and clean tub filter (Fig.8C).
- With Drain Cycle (Optional): Remove integral filter (Fig.7), remove overflow (Fig.9), close door, select "dr" cycle, press START (3). Machine runs a drain cycle and switches off. Clean tub filter (Fig.8C) if necessary.
- Turning Off: Press ON/OFF (1).
- Resin Regeneration (Optional): When "SLT" warning appears, add approximately 700g of large-grain kitchen salt to the container (Fig.11) using the supplied funnel. Fill with water first on initial fill.
- Display Information: Press PROGRAMME SELECTION (2) for five seconds to view wash temperature ("t"), rinse temperature ("b"), and total wash cycles ("CC").
- Viewable Messages: Includes "do" (Door open), "EC" (Number of cycles carried out), "b" (Rinse temperature), "End" (End of cycle), "t" (Wash temperature), "AS" (Automatic start enabled), "Pr 1/2/3" (Short/Medium/Long wash), "Lo" (Continuous wash), "dr" (Final drain), "rEG" (Regeneration cycle or request), "SLT" (No salt in the softener).
- End of Shift: Drain machine, disconnect power, close water cock, perform maintenance, and leave door ajar to prevent odors.
Maintenance Features:
- General Rules: Always drain water, shut off power, and close water supply cock before maintenance. Do not use water under pressure. Clean body panels when cold with steel-specific products. Drain boiler and wash pump if there's a risk of ice.
- Cleaning: Regular sanitizing treatment with non-corrosive commercial products is recommended.
- Cleaning the Filter Unit: Perform daily or when filters are dirty. Remove and clean baskets, empty tub, remove and clean all filters. Do not use abrasive products. Restore all parts.
- Cleaning the Arms: Wash and rinse arms are easily removed for cleaning nozzles and preventing blockages (Fig.10). Undo nut R, remove arms, wash under running water, clean nozzles with a toothpick, clean arm rotation pins and drainage area. Restore arms and check free rotation.
- Self-Diagnostics: The machine displays error codes for various malfunctions, such as "Er 01" (No rinsing), "Er 02" (No drainage), "Er 03" (Rinsing temperature reset fault), "Er 04" (Water filling in tank fault), "Er 05/06" (Tank thermometer fault), "Er 07/08" (Boiler thermometer fault), "Er 09" (Boiler loading time out), "Er 21" (Insufficient rinse), "Er 22" (Tank temperature reset fault), "Er SF" (Electro-mechanical safety device), and "Er SL" (Level safety switch). Switching the dishwasher off and on again "resets" signals. If problems persist, contact an Authorized Service Centre.
