Troubleshooting

WARNING! Steam generators may have several electric circuits.
Make sure that the device is completely dead before any troubleshooting operations.
Checks and troubleshooting.
In case of malfunction check that:

the control panel and the steam generator are installed according to the connection diagrams

the steam generator is installed properly according to this instruction manual

the downpipe has adequate fall towards the drain
 the dirt filter is clean. The filter is in the incoming water connector. Open the pipe connector for cleaning, remove the
filter and remove all the chalk and dirt from it.

there are no water pockets in the steam pipe or in the outgoing air conditioning pipe.
 there are no sharp bends in the steam pipe (bend radius must be at least 50 mm).

any tap on the incoming water pipe to the steam generator is open.

the steam room's structure and air conditioning match the installation and building

Possible causes and suggestions for fixes
Warming up takes abnormally long.
Cause: Inadequate power output of the steam generator. See output chart.
Action: Replace with more powerful steam generator.
Cause: Excessive ventilation of the steam room.
Action: Reduce ventilation so that it is 10-20 m³ per person per hour.
Cause: Blown fuse in the electrical cabinet
Action: Replace the fuse.
Action: Replace the heating element
Cause: The sensor is too close to the steam shower.
Action: Move the sensor to another location or redirect the steam shower.
The steam room does not warm up or there is no steam.
Cause: Blown fuse in the electrical cabinet
Action: Replace the fuse.
Cause: No water is coming to the steam generator.
Action: Open the incoming water tap.
Cause: The control panel is not set up right.
Action: Check the time and temperature settings.
Cause: Dirt filter is blocked.
Action: Remove the dirt filter from the incoming water connector and clean it.
Cause: The electromagnetic valve for the incoming water is stuck.
Action: Remove the electromagnetic valve and clean it.
Cause: Too much chalk has accumulated in the steam generator's water tank. See test 1.
Action: Clean the water tank and surface sensor's pin, and replace the heating elements, if necessary.
Cause: The steam generator is connected for incorrect voltage.
Action: Check the voltage and the steam generator's connections. See Connection diagram.
Cause: The overheating protector has tripped. See test 4.
Action: Check and fix possible faults in the steam pipe, e.g. blocks caused by several sharp bends, water pockets or
significantly reduces inner diameter of the pipe. It is also possible that the tank has been filled with chalk accumula-
tion or impurities. See the previous entry.
Cause: Fault in the circuit board, control panel or electromagnetic valve.
Action: Replace the faulty part.
See test 2.
