    Default GI1500PHB6 cavitating noise and cleaning indicator

    Model Number: GI1500PHB6
    Brand: Whirlpool
    Age: 6-10 years

    Bought this unit last year at an estate sale and was so pleased that it worked so well. This summer I started hearing a noise that could only be stopped by adding more water to the filler tank. Only happened every now and then so no big deal. Now it is doing it all the time and now after running for 8 hours or so the cleaning light is blinking. Ran thru the cycle even using specified cleaner. Pulled pump and it is in good working condition. I have read many articles and posts on these ice makers and I have seen lot's of posts on broken grids and external pumps but have seen very little on my issues. I suspect main board or filler valve. Toss this dog and bone and help me get it back up and running.

    Measure the resistance of the coil on the water valve. It should be 277.5Ω Turn the machine off then unplug it for a minimum 120 seconds (2 min). Restore power and turn machine on. Measure the voltage at the water valve (120 VAC).

    Default Partial Success

    Thanks for the direction. Coil measured 280 ohms and voltage was dead on. While I was there I pulled the valve. I disassembled it and checked for blockage. The screen was coated and the main inlet was partially plugged by hard water deposit.

    Cleaned it all up inspected the seals and put it back together. So far so good but it would usually make a full load of ice before it would start starving for water and then the cleaning light would come on. I will update if this is or isn't the solution.

    Well after a quiet 10 hours and a bin full of ice the pump starving for water sound returned. Just for grins I turned the unit off and then back on. It started filling and the noise abated. 12 hours later all is still quiet. Not sure what that means but that is what is going on now.

    Check for 120 VAC at the water valve

    Sounds like the control board may be the problem: WP2304016 Relay Board

    Angry Nope not today

    While I was out of town on business my wife called someone in to fix the ice-maker. She said she was tired of me wasting my time on it. Well they came in and replaced the logic board and 12 hours later after a bin full of ice the pump was once again starving for water. I have not called them back out but after looking at the bill I am sure I don't want to.

    I think at this point the only thing to do is to actually replace the water inlet valve and see if that is the culprit, beyond that I am at a loss of ideas and enthusiasm for throwing any more money at this unit.

    Did you check if you have 120 VAC at the water valve?

    When I pulled the valve I remember checking the ohms but may have missed the voltage at the plug. What does the lack of proper voltage at the pump indicate?

    Why is the pump starving for water? If the valve is getting 120 VAC and not letting water in, bad valve.
