Folks,
I have an old but good Microm/Hacker HMP300 tissue processor which is
refusing to behave at the moment.
When trying to run it fails at diagnostic #3, A more detailed check reveals
the problem to be a "Station valve driver fail off" error for station 14
(the xylene cleaning step). I have obtained and replaced the valve to no
effect, I swapped the electrical connections between station 14 and 15 (I
still get the same error for station 14) and am at the end of my patience
with the wee beastie.
I have the following questions:
1. What is causing the problem?
2. How do I fix it?
3. Is there anyone out there who remembers these machines and can fix
the problem? I am located just North of Seattle.
4. Failing that, does anyone have a service manual and/or parts I can
borrow or buy?
Thanks in advance for your help
Simon
