Problem wbdiff SNF 2012-09-17 15:21:48: HCl bath has Low liquid level problem

[qran at snf.stanford.edu]

as reported by previous user, the HCl bath shows a Low liquid level (LLL) problem in the temp range 30C to 40C, and heating can't processed unless you keep pushing the heat button. 
Also even if the temprature is in the right range, during the process, the LLL alarm rings again.
