Water Level Sensor Replacement - GREAT! by (Millerton NY US)

I was getting SIX flashes on the RED Service Light - so the unit was not working. Took apart and cleaned the Water Level Sensors ... Did not help at all ... This replacement kit went in fast and easy (make sure you have a Torx screw driver.) Fixed the problem and the TrueSteam works great now. Saved a $250 service call by a technician! :)

New sensor solves problem by Bob Cherry (Idaho Falls ID US)

My humidifier was giving me the "two blinks" error code and a couple of times the six blinks code. Following the service guide I cleaned the electrodes with warm soapy water and then with a wire brush in a Dremel tool even though they looked fine. Although our local water is very hard, I have a water softener and there was no sign of scale buildup on the sensor elements. I also confirmed electrical continuity from the electrode tip to the connector on the wiring harness. Everything looked as it should, but I still got the error code within a day of reinstalling the sensor. So, following the service manual I replaced the sensor even though I suspected that the problem was actually in the humidifier's circuit board. The new sensor has worked perfectly for about ten days now. I'm telling this long story because I was hesitant about spending $57 plus shipping to replace a piece that had no apparent defects. However, doing so solved my problem.

Not sure it was needed... by J Schaefer (Calgary Al CA)

Overall, I'm happy with True Steam. It is certainly superior to our old rolling drum system. Our municipal water is considered hard (for a good explanation, Google search "Calgary hard water"). I need to clean out our True Steam once per month. In November, there was much scale and the warning light suggested a sensor failure. I cleaned the water tank, removed the sensor, and bathed both in CLR (sometimes I use diluted vinegar). After re-assembling the unit the red light continued to blink twice indicating a persisting water level sensor failure which prompted me to order this part. I was somewhat surprised as there appeared to be no damage to the sensor, it was thoroughly descaled, and there does not appear to be any sensitive circuitry in this part (I could be wrong). After ordering the part, I realized that I may not have depressed the 'Reset / Go' button and after doing that, the light stopped and the unit has been working properly since (3 weeks have passed). I don't mind having a spare senor on hand as I suspect that sooner or later it will need replacing. However, it appears that I did not need need this part. I leave these observations for others to consider. My trouble shooting guide does describe how to clean the tank and recommends sensor replacement. I followed the manual. However, I have no special skills, this post is provided in good faith, and I cannot take responsibility for any action or lack of action taken by readers. Please follow all safety procedures, particularly as it relates to electricity and water.

This was a real no brainer. Finding the sensor was quick and easy. I thought the price was a bit high, but they provided the part with additional parts that it mates with. Unexpected, but they might have been part of the failure when I thought about it. They also got it out quickly to avoid delay, and too many more days of extra dry air. All in all good job Honeywell team. Thanks!
