How to Fix / Troubleshooting
Safety first: Turn off and unplug the machine. Allow pressure to dissipate before working on the steam circuit.
- Operate valve fully: Turn the steam knob fully open and closed several times to dislodge minor debris.
- Descale steam circuit: Run descaler through the steam function to dissolve scale on the valve seat.
- Disassemble valve (advanced): Remove the steam knob and valve assembly. Inspect O-rings and seals; replace any that are flattened or cracked.
- Inspect valve body: If the valve body is cracked or pitted, replace the entire steam valve assembly.
After reassembly, test for leaks with the machine at full temperature and pressure.
