Hi  Allen

We had a similar problem with our ALFExpress II. As you know
Amersham-Pharmacia are now GE, but still support ALFExpress II (at
least with parts) and possibly ALFExpress. Check on their site and
contact someone from the support group.
Does the pump work ?. In our case the thermosensor was broken which
made the pump and the heater didn't work too. This kind of sensors are
unspecific and very cheap and any electroengeneer would replace them.
Here is the link to the site:

I hope this helps.
