Gino59 Posted October 6, 2021 Report Share Posted October 6, 2021 Good evening everyone, i have had this tub for a good 10 years , its been well looked after but she is now giving me a little test. i cam home last week to find it was not heated an flashing sns message, so the good old rest and off she fired and was good for a few days then the same. i had one very odd alarm code that said dry but that has not poped up since just when it cuts out the sns message. Tonight i had a look, i checked the a and b sensors and both read 23 ohms at around 28 degrees, so for me nothing odd between the 2. has anyone had any issues like mine that they could help me with, even some test data for me to check. i have meters and mfts if needed. look forward to hearing back Gino Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted October 7, 2021 Report Share Posted October 7, 2021 Sensors are in thousands of ohms, so 23 is a problem. You need a very accurate reading as a few hundred ohms difference can cause errors. These errors can also be from low flow, as with a clogged filter or pump issue. Remove filter first and see what it does. Quote Link to comment Share on other sites More sharing options...
Gino59 Posted October 7, 2021 Author Report Share Posted October 7, 2021 It could well be hundreds it was dark my glasses steamed up but both were the same value. Do you know or have a value chart for these. Quote Link to comment Share on other sites More sharing options...
