7.4 Water leakage in the iron
Firstly, identify where the water is leaking from:
- Through the soleplate openings: In this case it is not a leak but
a possible defect in the steam generation (it does not reach the
temperature, condensation in the hose, etc.)
- Between the plastic parts: In this case, it is a water leakage.
In the majority of the cases, water leakages are due to an incorrect
coupling of the hose or a faulty hose (manipulated, porous, etc.)
7.5 Water leakage in the steam station
The water leakages of the steam station can mainly be located in:
- Water chamber cover seal
- Hose connections or faulty tubes
- Cracked boiler
- Incorrect sealing in solenoid valve joints
7.6 No steam is produced
1. Switch on the steam unit and check if some led lights. If not,
checked wiring (power boiler, ON/OFF switch, electronic
wires, etc) and continue with the next step.
2. Check continuity of heater. If no continuity, replace the boiler.
3. Check continuity on thermofusible. If no continuity, replace
thermofusible and NTCs.
4. Check resistance of the NTC at ambient temperature. If the
values are out of range, change the NTCs.
NTC - check: nominal value 100k
Ω
at 20ºC
5. Check the pump operation. If it doesn’t connect directly,
change the pump.
6. If all above is correct, but the boiler isn’t heating, change the
PCB.
7. Check the operation of the steam button micro-switch
Switch – check. Measure with a tester in the
monotube connector, that there is continuity.
8. Check the mechanical operation of the switch.
