These water flow related problems can cause the heater to deliver less than its full output, or to fail to ignite or to shut down completely. Problems are stated in upper case, bold face. Most common causes for the problems follow in order of likelihood. The suggested solutions require that the cover be taken off. To do this, pull off the temperature knob and unscrew and remove the temperature knob collar. Pull main cover out toward you and lift up and out. NO SPARK AT THE PILOT 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. 11. 2. Bad electrical connections. Be certain that all electrical connections are clean, tight, and free of any moisture. 3. 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 125FX 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. 4. Bad fuse Check the viability of the fuse (see Fig 10 (#4) for location of fuse). Replace if necessary. 5. Water inlet filter is clogged Water flow is restricted, preventing flow needed to activate heater. Clean water inlet filter screen. 6. 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. 7. 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. 16 (#1) for location and see Fig. 15 for adjustment. The microswitch may need to be replaced. G871_212 Adjusting screw Fig. 15 - microswitch adjustment Pilot does not spark with Pilot always sparks water flow without water flow 1 Close water tap 1 Close water tap 2 Remove screw cap and 2 Screw in adjusting screw unscrew till sparking starts until it stops sparking 3 Screw in turning one and a 3 Continue to screw in half turns turning one and a half turns more 8. Cold incoming water connection made to wrong side of heater Make sure cold water inlet connection is on the right side when you are facing the AquaStar. 9. 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. 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 needs to be replaced immediately. 10. 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. 11. Reset electrical power to heater If resetting the electrical power corrected the symptom then likely the unit’s Safety Spill switch (Flue gas safety device -#9 on page 19) had tripped from a flue blockage during the previous usage. Inadequate combustion air to the room area can also cause the unit to improperly vent. Improper venting or insufficient combustion air must be corrected. Consult a licensed professional to inspect the installation. SPARKS APPEAR AT PILOT WHEN HOT WATER TAP IS TURNED ON, BUT PILOT AND BURNERS WILL NOT IGNITE 1. Air in the Gas Line Note: Normally this is a problem only at the time of initial installation, after the pipes have been worked on, or after a propane tank has been allowed to empty, or after the heater has been shut down for a long time. Bleed all 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 unlock the regulator. Note: The regulator furnished with the heater is exclusively designed for low gas pressure (less than . psig). Excessive pressure will lock it up. Locking usually happens when the gas pressure between the gas tank and the water heater’s gas regulator has not been properly regulated. See Page 2 for recommended correct gas pressure. To unlock a regulator, consult your gas supplier or call CEC. 3. Pilot orifice clogged 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. See Fig. 14. 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. 15...
