Hello,My name is ***** ***** I will do my best to assist you. I am looking over your question now and will respond shortly.
Ok so everything works BUT it refuses to heat over 81F
This will be the temp sensor. It works but is out of calibration.
Are you familiar with replacing temp sensor?
You can tell by adding cold water....measuring heater amps...feeling the heater..
Fill with some cold water.....if it still takes it to 81 it is a sensor..
You can ohm the sensor to check accuracy. Let me get you a chart..
The beauty of ohming a sensor is the value should always correspond to a temp.
Like a sensor at 81 f should always be 27540 ohms.
Fill with cold..take sensor reading and see if heater kicks on..
the triple dash is watch dog error...a sensor or limit has tripped as a safety precaution.
This can be by a sensor that doesnt read temp right and lets unit run too high.
With triple dash you will want to use the diagram and check the limits...and as far as testing..remove the wires from board and test across wires.
you should be able to find at your local supplier as it is a very common part.
Whenever testing for ohms, power is always off.
You see on ohms, the battery in the meter sends its power out one lead and measures what comes back on the other. If 0 it means no battery power came back. If a number it represents the resistance the battery power had to go through to get back...as a sensor warms or cools the resistance changes..it will match the chart I gave you (should)
Lets say the temp is 81 but the sensor reads 17490
The sensor "thinks" it is 100 degrees but it is not...if the ohms do not match the temp in chart = change sensor
You are very welcome and I wish you the best
I do not know which control panel you have, but is the sensor arrangement made into one plug?
The sensors should read the same at the same temp..what does the other read?
correct..one is inflow and one is out flow. But do the same job just 2 different places
outflow....it would simulate the heater is overheating which causes the watchdog alert
Hi there, I'm Cole. I see your last tech had to leave conversation but from what I have understood from your conversation I would replace both sensors. A lot of the time these balboa or gecko brand sensors are sold as a pair and that's what we do is replace both. If your narrowed down to the sensors like this just do them its usually not that expensive to purchase the pair.
this one does look like a single sensor so you could replace the outgoing one and test the tub if that does not work switch it to the other and re install the original good one back in its original location. :)
Ok so talking to my guys i need a different number. so there is either a white tag on the board itself or even a tag on a chip on the board. if i have those i can find out exactly what sensors. thanks for your patience.
if your unsure what numbers take some closeups of any tags you see on the board its self. thanks
ok let me do some checking for you. are you asking why you got referred to me or to somebody new again?
no i am here to help. i did get the pictures. i sent them over to my guy i will let you know.
