Troubleshooting

Note: in case of problems, always consult the troubleshooter!
If the water in the device is no longer heated, first check whether the plug is properly
connected to the wall socket and whether the fuse of the device group is still working.
For all other failures, please consult the troubleshooter.
If the device no longer works because it was connected without being filled with water
first, follow the troubleshooter. The device has been overheated and needs to cool down,
or possibly repaired.
If the device has been reset several times, but still does not work, please contact the
Hotto service line.
6. Disconnect and drain boiler
When the boiler needs to be disconnected follow these steps:
1. Put the boiler in standby mode by pressing the standby button (B3) untill the standby
LED turns orange.
2. Drain the boiling water with the boiling water knob (K1) untill cold water comes out
of the tap.
3. Turn off the boiler with the switch on the back side of the boiler (B5) and pull out the
plug from the socket.
4. Close the stop valve from the safety group.
5. Relief the pressure from the boiler by opening the boiling water knob (K1) and warm
water lever (K2) untill no (cold) water comes out of the tap.
6. Now the hoses of the boiler can be disconnected. Please note that some water may
come out of the cold water hose (H2).
7. Place the boiler near the sink.
8. Blow on the warm water hose (G2) from the boiler and the remaining water will flow
out of the boiler through the cold water hose (H2).
It is likely that a small amount of water will remain in the boiler.
