1. On/Off switch is not "On" (Position I).
The On/Off switch is located behind the flipdown cover
plate on the front panel strip. See fig. 9.
2. Water flow is not sufficient to activate heater.
Water flow rate at faucet is below minimum flow needed
to activate heater. When temperature adjustment knob is
turned all the way clockwise, the AquaStar model 125X
requires 1/2 gallon per minute flow to activate the heater.
As a reference, this is a flow which would fill a quart jar in
30 seconds. If the temperature adjustment knob is turned
fully counterclockwise, a flow rate of 1.1 gallons/minute is
required to activate the heater.
3. Water inlet filter is clogged
Water flow is restricted, preventing needed flow to activate
heater. Clean water inlet filter screen.
4. Cross over in water lines
To confirm there is no cross-over in the plumbing, shut off
the cold water supply to the AquaStar water heater and
open a hot water faucet. There should not be any water
flowing at that faucet. Water running is a sign of a plumbing
cross-over. Consult your plumber.
5. Batteries are weak
The LED light (seen through the peephole in the coverplate
on the front panel) flashes when the batteries are less
than 1.2 volts. Replace batteries with D cell (1.5 volt) long
life alkaline batteries as shown in fig. 9.
6. Microswitch needs to be adjusted or replaced.
If you do not hear a click when a tap is opened, the
microswitch needs to be adjusted. See Fig. 12 for
adjustment, or replace the microswitch if the heater has
been in use for some time.

7. Cold incoming water connection made to wrong
side of heater
Make sure cold water inlet connection is on the right side
of heater when you are facing heater.
8. Water valve parts may be dirty or components
damaged
First check that venturi is free of dirt particles. Water valve
and component parts must be totally free of dirt. In hard
water areas, mineral deposits can eventually (3-5 years in
hard water areas) corrode the water valve parts to a point
where they will need replacing. Any sign of moisture at
the bleed hole is a sign that the water valve
components need to be replaced immediately.
9. Loose connection at the ECO
Ignition sparker will not operate if the electrical circuit is
interrupted. Check that the connections to the ECO are
secure and tighten if necessary.
SPARKS APPEAR AT PILOT WHEN HOT WATER TAP
TURNED ON, BUT PILOT AND BURNERS WILL NOT
IGNITE
1. Air in the Gas Line
Normally this is a problem at time of initial installation, after
the pipes have been worked on, or after a gas supply line
has been allowed to empty. Bleed the air trapped in the
gas line by turning the hot water faucet on and off until the
air has been cleared from the line.
2. No gas to the AquaStar
A. Gas cock on gas line may not be open
B. Gas regulator may be shut or damaged. Replace or
unjam the regulator. Note: The regulator furnished with
the heater is exclusively designed for low gas pressure.
Excessive pressure will lock it up. Jamming usually
happens when using propane gas if f the gas pressure
between the gas tank and the water heater's gas regulator
has not been reduced. See Page 2 for recommended
correct gas pressure. To unjam a regulator, consult your
gas supplier or call CEC.
3. Pilot orifice or gas valve is dirty
Clogging of the pilot burner can be caused by dust in the
air or dirt in the gas. The pilot orifice or gas filter may need
to be cleaned or replaced.
4. Water valve assembly needs to be checked
If the pilot orifice is clean, the water valve assembly should
be checked. The adjustment screw on the water valve
micro-switch may not be tight enough (Fig. 12). Remove
central cap beneath micro-switch assembly, carefully
loosen the adjustment screw until the pilot light ignites. At
that point retighten the screw one and a half turns.
5. Pilot electrovalve switch may need to be replaced
(See Fig 13).
Call CEC.
6. Electronic Control Box may need to be replaced
(See Fig 13).
