How to fix small drops flowing out of the water tap on La San Marco Coffee Maker?
Small drops flowing from the water tap usually indicate a leak in the solenoid valve. Check the solenoid valves (hot and cold water) and replace as necessary.
What to do if the safety valve tips to release steam on La San Marco Coffee Maker?
The safety valve may release steam due to: * A malfunction in the electrical system where the heating element is always connected. * Pressure increase in the boiler. The safety valve trips at 2 to 2.5 bar. In both cases, check the wiring that feeds the heating element and the pressure switch.
Why are the programmed servings of espresso coffee not constant on La San Marco Coffee Maker?
Inconsistent espresso servings can occur due to: * Abnormal operation of the electronic control unit or displacement counters. Program the serving doses separately on each dispensing unit. If the problem persists, replace the volumetric meter of the affected dispensing unit. * A leak from the serving unit solenoid valve. If so, replace the solenoid valve of the serving group. * Clogged water dispensers. Check the water dispenser.
What to do if La San Marco Coffee Maker boiler is full of water and water flows out of the safety valve?
If the boiler is overflowing, it is likely that one of the outflow lines from the boiler or a circuit of the unit has a leak. Check the autolevel circuit, the manual charging button, and the boiler heat exchangers. Replace any worn or damaged parts to stop the leak.
Why does the La San Marco Coffee Maker machine emit a whistle after serving coffee?
A whistling sound after serving coffee can be caused by: * Faulty operation of the expansion valve. Check the expansion valve and replace it if necessary. Calibrate the valve at 12 bar. * High pump pressure. Check the pump operating pressure and calibrate the pump at 9 bar.
What to do if the La San Marco Coffee Maker was started but the water in the boiler does not warm up?
If the water isn't heating up, it could be because: * The electric heating element is defective or not connected. Check if the heating element is connected to the power supply. * The main switch is turned to position 1. Ensure the main switch is turned to position 2.
Why is it not possible to program serving quantities on La San Marco Coffee Maker unit 1?
The inability to program serving quantities on unit 1 may be due to abnormal operation or a defective displacement meter of unit 1. Check the control unit-displacement meters electrical wiring and replace the volumetric counter.
What causes the displacement meters alarm on La San Marco Coffee Maker?
A displacement meter alarm could indicate: * Jammed or defective displacement meters. Replace the volumetric counter. * Defective wiring. Check the wiring and its connections, the control unit, and the fuses.
What causes the overfill alarm on my La San Marco Coffee Maker?
An overfill alarm may be caused by: * A malfunction in the automatic level circuit. Check the hydraulic circuit of the autolevel. * A leak in the button for manual water filling. Check the hydraulic circuit of the autolevel. * A leak in the heat exchangers. Check the hydraulic circuit of the autolevel.
What to do if the La San Marco Coffee Maker machine is switched on but the electronic control is out of order?
If the electronic control is out of order, it could be due to: * Defective electric wiring of the electronic control unit. Check the electrical wiring, the electronic control unit, and its components. * A defective electronic control unit. Replace the electronic control unit.
