How to Fix / Troubleshooting

Safety first: Unplug the machine and allow it to cool fully. Steam circuits can cause severe burns.

Clean the steam wand: Remove the frothing tip from the Kenwood steam wand (if detachable). Soak it in hot water with a little detergent, then clear the nozzle holes with a fine needle.
Run steam purge: After reassembling and plugging in, select steam and open the steam knob fully to purge air and any residual water. If E08 appears immediately, stop and unplug.
Descale the steam circuit: Run a descaling cycle ensuring that part of the cycle is directed through the steam wand, as per the user manual.
Do not open boiler: Do not attempt to open or disassemble the boiler or steam thermostat yourself; this involves pressurized hot water and mains voltage.
If E08 persists: The steam thermostat, NTC sensor, or steam solenoid valve may need replacement. Contact a qualified service technician.

E08 appears and the machine reports a steam system fault; no steam or frothing.
