TROUBLESHOOTING
Problem Possible cause of	fault Possible solution
There is leakage/drip- ping from the safety valve/there is often water on the floor by the cylinder in the morning	Pressure reduction valve, water me- ter or blocked non-return valve on the water intake. Water pressure into the home is too high.	Fit AX expansion vessel with absorbs expan- sion during heating, and fit pressure reduc- tion valve for stable water pressure inside the home. The pressure reduction valve is adjusted in according to the pressure in the expansion vessel. Contact auth. installer.
	The safety valve is worn or there are particles stuck between the mem- brane and the valve seat because the water is dirty	Try to flush with water through the safe- ty valve. Open valve approx. 1 minute. See section 5.2. If the valve still leaks, it must be replaced. Contact auth. installer.
	Leak from heating element.	Verify as follows: a) cut the electric sup- ply, b) unscrew the cover, c) visually check whether there is a leak from the heating element. If so, replace the gasket/heating element. Contact auth. installer.
No hot water	Power supply interrupted.	Verify that the fuse is on / the plug is plugged in to the wall contact / the earth breaker has not tripped.
	Thermostat has cut out.	Press the 'RESET' button on the safety thermostat; see 'User guide'.
	Heating element is defective.	Replace heating element. Contact auth. installer.
	Leak in hot water pipe	Verify as follows: a) close the mixer valve, b) wait 2-3 hours, c) feel the mixer valve to see whether it is hot. If so, there is a leak in the hot water pipe or elsewhere. Contact auth. installer.
Not enough hot water High consumption in the home.		Raise the temperature on the thermostat to 85°C; see 'User guide'. Switch to a larger OSO water heater. Contact auth. installer.
Not high enough tem- perature	The mixer valve is set for low tem- peratures.	Raise the temperature on the mixer valve; see 'User guide'.
	The thermostat is set for low tem- peratures.	Raise the temperature on the thermostat to 85°C; see 'User guide'.
	Change from cold to hot water in taps.	Contact auth. installer.
Fuse/earth breaker trips repeatedly	Possible fault in the heater's electri- cal system.	Verify as follows: a) cut the electric supply, b) unscrew the cover, c) visually check the junction box for any problems. If so, con- tact auth. installer to check. Fit the cover.
Long time before the water reaches the tap	Long stretch of pipe from water heater to tap.	Fit circulation wire or heating cable to HW pipe. Or fit an auxiliary heater by the tap. Contact auth. installer.
Knocking in the pipes when the hot tap is closed	Large pressure increase when the tap is closed quickly.	Completely normal. Fit AX expansion ves- sel if troublesome. Contact auth. installer.
