F1 error relay circuit failure

Hi This is the Alarm system watchdog circuit :

The system has detected a failure in the internal watchdog element , relay circuits and will atcivate a cancel feature. F1 will be displayed in the time digets and will beep until the cancel button or another funtion is selected. An F1 failure could be detected in cook or time of day mode. With an F1 failure the ERC is picking up a comand to supply heat without receiving an input from the membrain. The watchdog circuit is designed to prevent this.
If the beep continues after pressing cancel check the main control ERC board.

Dacor oven beeps and shows F1 code

-F1- Alarm “System Watchdog Circuit”
The system will detect a failure in the internal watchdog element relay circuits and will activate a
cancel feature. F1 will be displayed in the time digits and will beep until the cancel button or another
function is selected. An F1 failure could be detected in cook or time of day mode. With an F1 failure
the ERC is picking up a command to supply heat without receiving an input from the membrane. The
watch dog circuit is designed to prevent this.
If the beep continues after pressing cancel check the main control (ERC)

Spa / hot tub does not heat

Your temperature control is way out of calibration or, it's wired wrong. Remove it and check it in a glass of water. Use an ohm meter across the heater wires. As you add hot wwater, the heater contacts should open.

Redout on jacuzzi spa model j340 has --- code.has been working

The condition you see on the topside control is known as "watchdog" Which usually means that the spa thinks it's "overheating"
Turn off the power to the spa for a couple of minutes, then restart, Watch the topside control if the temp. starts to climb & read a lot hotter than the actual water temp. Then it goes into watchdog, most likely you have a bad temp sensor. In some cases just resetting the spa will clear the watchdog & everything works fine. (Voltage fluctuations, "spikes" can freak out the electronics & the tub goes into watchdog to protect itself) If the spa immediately goes into watchdog when you reset it, you might have a bad board. (Let's pray it's not) 90% of the time it's a bad temp. sensor.
