Upon refilling and turning the temperature controller on, the low liquid alarm sounded and remained on, even when liquid level was normal (between red bars and stencilled letters). Alarm did not turn off whether the temperature controller power was turned off and on, the bench was disabled and re-eneabled, or more acid was added. Since alarm was on, the bath did not heat. When I last used this bench (4-5 months ago), there were problems with the LL alarm going off every few minutes, but the bath was still able to heat in between these (false) alarms. Has the LL sensor finally died?
