Frequently Asked Questions - 7280.0022 CombiSteel
How to connect the CombiSteel 7280.0022 dishwasher?
The electrical connection must be carried out by a qualified electrician. Use a 30 mA magnetothermal differential switch with a minimum opening of 3 mm. Connect the power cable after installing all panels. The cable must be connected to an equipotential terminal at the back of the machine.
What are the requirements for the water supply?
Feed water must be between 10 and 50 °C (25 °C max with softener). Dynamic pressure must be 200–500 kPa (2–5 bar) for mains pressure versions, or 100–500 kPa (1–5 bar) with atmospheric booster. Recommended hardness is 5–20 °f. Install a pressure reducer if pressure exceeds 500 kPa.
How to perform the first start-up?
Check the connections, open the water tap, turn on the appliance. Adjust the detergent and rinse aid dispensers according to water hardness. For the electronic version, follow the on-screen instructions: select the language, set the hardness, and preload the dispensers. Run 3 empty cycles before use.
What to do in case of 'TANK FILLING' error (Alarm 01)?
Check that water is coming to the tap and that it is open. Ensure that the overflow is in place and not obstructed. Check the rinse arm nozzles and the fill tube. If the problem persists, call a technician (faulty solenoid valve or pressure switch).
How to use the self-cleaning function?
Once washing is complete, dishwasher on and door closed, press the drain pump button (3) for 2 seconds. The display shows 'REMOVE OVERFLOW!' and 'TANK DRAIN'. Open the door, remove the overflow. The tank drains, then self-cleaning begins (automatic rinse). When the tank is empty, the appliance turns off.
How to adjust water hardness on the electronic version?
During first start-up, the display shows 'WATER HARDNESS' with a default value (25 °f). Use the + and - buttons (5 and 6) to change the value according to measured hardness, then press the confirmation button (7). This data is memorized.
When and how to fill the softener salt tank?
Fill the salt tank as soon as the display shows 'SALT EMPTY!' or the yellow light flashes. Use only coarse kitchen salt. Unscrew the cap in the tank, add 1 kg of salt with the funnel, then pour 2 glasses of hot water to dissolve the salt. Clean the gasket and close.
Why is washing quality poor?
Check that the detergent is suitable and properly dosed (follow the manufacturer's instructions). Clean the turbine nozzles if clogged. Ensure the tank temperature reaches at least 55 °C. Check the pump filter and the wash cycle: if too short, repeat the cycle.
How to maintain the dishwasher after long inactivity?
Before using after a few weeks of inactivity, run 3 cycles with clean water. Manually check that the wash and rinse pumps turn freely by inserting a screwdriver into the notch of the motor shaft on the ventilation side. Replace the tank water every 25 washes or twice a day.
What personal protective equipment (PPE) is recommended?
Wear appropriate gloves (high temperature and corrosive substances) during maintenance and contact with hot dishes. Use protective shoes for handling. Protective clothing may be necessary when cleaning with chemicals.
