TEST 1.
Cause: The steam generator is wired up for the wrong
voltage.
WARNING! SEVERAL SUPPLY CIRCUITS. CHECK
THAT THERE IS NO CHARGE IN THE MACHINE
BEFORE DOING ANY MAINTENANCE WORK!
Test for calcium deposits in the reservoir.
Solution: Check the voltage and the connection to the
generator – see diagram.
Unscrew the capping nut at the top of the steam
generator. Lower a torch bulb, wired up to a battery, into
the hole. Inspect the illuminated tank through the hole. If
there is a layer of calcium carbonate extending more than
three centimetres above the bottom of the tank, the
reservoir has not been serviced as prescribed with regular
applications of a de-scaling agent.
Cause: The temperature limit control has been triggered,
see test 4.
Checking and fault-finding.
Solution: Check and remedy any faults on the steam pipe,
such as a blockage due to several sharp bends, water
pockets or greatly reduced internal diameter. The tank
may also be clogged with limescale; see above.
In the event of faulty operation, first check
the following:
• are the control panel and steam generator wired up in
accordance with the wiring diagram?
The problem may also be that the emptying and flushing
systems are no longer operative. If there is a switch along
the feed cable to the steam generator, check that this has
not been used as an OFF switch after steam bathing. A
switch in the feed cable must not be switched off until at
least 80 minutes after the control panel has turned off the
system.
Cause: Flaw in the circuit board, control panel or
magnetic operated vent.
• is the steam generator correctly installed in accordance
with these instructions?
Solution: Replace the faulty component.
•
does the drainage pipe slope down properly towards
the waste outlet?
Hot water runs from the steam head. Little
or no steam in the steam room.
• is the filter clogged? The filter is located at the point
where incoming water is fed into the generator. To
clean the filter, disconnect the feed pipe, remove the
filter and rinse it free from particles of calcium
carbonate and other deposits.
Cause: The solenoid valve for incoming water has stuck,
due to accumulated deposits of foreign bodies or an
electrical malfunction. See test 3.
Make sure that the automatic emptying function is
working, by placing a suitable vessel (capacity approx.
3 litres, 5 pints) under the drainage valve. Switch on the
steam generator and let it remain on for 15 minutes.
Switch off the generator in exactly the same way as you
always do when turning off the steam bath for the day.
Wait at least 80 minutes, and then check that the vessel
is full of water. If this is not the case, either the steam
generator has been incorrectly wired up, or the power to
the generator has been interrupted in some other way
along the cable from the electric supply to the generator,
or alternatively there is a fault in the drainage valve or the
circuit board
.
Solution: Remove the valve and clean it, or rectify the
electrical malfunction.
• are there any sags along the steam pipe or along the
ventilation duct leading from the steam room?
Cause: The solenoid valve is broken.
• are there any sharp bends in the steam pipe? (the
minimum permitted radius of bends is 50 mm, 2")
Solution: Replace the valve.
Cause: Malfunction in the circuit board.
• If there is a tap on the water supply to the steam
generator, make sure this is not closed.
Solution: Replace the circuit board.
Hot water comes out of the steam head in
spurts or in a slight, even flow mixed with
steam.
• does the construction and ventilation of the steam room
comply with Tylö’s instructions?
Checklist
Cause: Small water pocket along the steam pipe.
with alternative causes of problems and suggested
actions.
TEST 2.
Solution: Eliminate the water pocket.
Cause: The steam pipe is uninsulated along too great a
portion of its length.
Temperature sensor test.
The steam room maintains the desired
temperature (40–50°C, 105–122°F), but no
steam is produced.
Soak a small towel in cold water. Hang the wet towel over
the thermostat sensor. If, within 20 minutes, the steam
generator has started to product steam continuously, the
equipment is not defective, but the thermostat sensor
(bulb) is located in an unsuitable position, or the
thermostat itself is set for too low a temperature. If steam
production does not begin, use the checklist to find out
the cause.
Solution: Insulate the steam pipe.
A continuous trickle of hot water from the
steam generator’s drainage pipe.
Cause: Insufficient ventilation in the steam room.
Solution: Increase ventilation. The ventilation is insufficient if
less than 10–20 cubic metres (13–28 cub. yd) of air per
person per hour is evacuated via the outlet vent. This
situation may occur if the outlet vent is not connected to
some form of mechanical extractor fan – or if the
ventilation duct is blocked by a water pocket.
Cause: The solenoid valve for automatic emptying has
stuck.
Solution: Switch off the steam generator. See what
happens again after an 80-minute pause. If the fault
persists, remove the solenoid valve for the automatic
emptying function and clean it.
TEST 3.
Solenoid valve check.
Cause: The air coming into the steam room is too warm.
Loud noises in the feed pipes when the
solenoid valve opens or closes.
Use the control panel to switch off the steam generator. If
water continues to trickle out of the steam head more
than 10 minutes after the control panel has been switched
off, the cause is dirt in the solenoid valve. Remove and
clean the valve.
Solution: Reduce the intake air temperature to 35°C (95°F).
Cause: The ambient temperature is higher than 35°C
(95°F).
Cause: The steam generator feed pipes are not
sufficiently secure.
Solution: Ensure that the ambient temperature does not
exceed 35°C (95°F).
Solution: Fix the pipes securely to the wall with pipe clips.
Cause: The thermometer is faulty or wrongly placed.
If the water stops running through the steam head within
10 minutes after the control panel has been switched off,
the cause is an electric fault (incorrect connection or
circuit board fault). Or, alternatively, excessive calcium
carbonate has accumulated in the reservoir. See test 1.
Cause: “Recoil” problems in the feed pipe (Pipe hammer).
Solution: The thermometer should be placed
approximately 170 cm (67") above floor level and as far
away from the steam jet as possible.
Solution: Replace a metre-long length of piping nearest
the steam generator with flexible piping, for example,
reinforced rubber hosing, which will withstand the
pressure.
The steam room requires an abnormally
long time to heat up.
TEST 4.
Safety valve opens or temperature cut-off is
activated.
Cause: The generator is not powerful enough. See table.
Steam pipe test if the safety valve or the
temperature cut-off is activated.
Solution: Replace the steam generator with one with a
higher heat output.
Cause: The steam pipe is blocked; see test 4.
Solution: Remove the blockage.
Disconnect the steam pipe from the steam generator.
Start the generator and let it remain on for about 1 hour. If
the safety valve or the temperature cut-off is not activated
during this test, there is a blockage along the steam pipe
which is preventing the passage of steam. Take the
necessary steps according to the information in the
checklist.
Cause: Excessive ventilation in the steam room.
Cause: The internal diameter of the steam pipe is
considerably reduced. See test 4.
Solution: Reduce the ventilation to evacuate 10–20 cubic
metres (13–26 cub. yd) of air per person per hour.
Solution: Replace the pipe or the pipe joint which is
causing the reduction (Internal diameter must be at least
12 mm, ½").
Cause: Blown fuse in the mains fuse box.
Solution: Replace the fuse.
Cause: The ambient temperature is lower than 15°C (59°F).
Cause: Sharp bends (“elbows”) along the steam pipe.
See test 4.
Solution: Increase the ambient temperature or replace the
steam generator with a more powerful one.
Solution: Get rid of “elbows” in the pipe. Bends are to be
gently rounded (minimum radius 50 mm, 2").
Cause: Heating element is broken.
Solution: Replace reservoir.
Cause: Large water pocket somewhere along the steam
pipe. See test 4.
Cause: The thermostat sensor is too close to the steam
jet. See test 2.
If, during service, you wish to empty the tank,
disconnect the spade connector on the emptying
valve and connect the 230 volts’ mains supply
directly to the solenoid valve.
Solution: Adjust the steam pipe to eliminate the water
pocket.
Solution: Move the sensor or change the direction of the
steam jet.
Cause: Excessive calcium carbonate deposits in the
steam generator’s reservoir. See test 1.
IMPORTANT: This operation may only be carried
out by an authorised electrician.
Neither steam nor heat is generated in the
steam room.
Solution: Replace the entire reservoir, including elements
and electrodes.
Cause: Blown fuse in the mains fuse box.
Erratic steam production right from the
start.
Solution: Replace the fuse.
Cause: The water is not reaching the steam generator.
Solution: Open the tap(s) connected to the piping to allow
incoming water to flow into the steam generator.
Cause: The thermostat sensor is wrongly placed in
relation to the steam jet. See test 2.
Cause: The control panel is incorrectly set.
Solution: Move the sensor or alter the direction of the
steam jet.
Solution: Check the time and temperature on the control
panel.
