Topic: Hottop Premature Dump (92 lines)
1) From: Mark J Bergh
Janet,
Had the same problem with my Digi-Hottop when it was near new.  I went
through a long trouble shooting process that Hottop customer service =
advised
me to follow; carefully charting temps at regular intervals throughout a
full 21:59 time cycle.  There was concern that using a Variac was =
causing an
overheated condition to trigger the early bean dump.  I typically set =
the
Variac for around 125V and fine tune it to 120V when the heater is full =
on;
you can tell using a voltmeter to monitor this.  May be more than you =
are
interested in doing to operate your Hottop but was part of my plan to =
have
all possible variables under control (at least as allowed with the =
Hottop,
until the new programmable unit that has now become available).
Turned out that I had allowed the main filter element to go unattended =
for
too long and it had began to impede the fan air flow enough to cause the
internal temps to exceed the maximum threshold.  I ordered new filters =
for
both the top (perforated steel cover) and the plastic slide-in one in
question: problem solved!
I have probably run over 200 lbs of beans through it to date and haven't =
had
another problem with the early dump.  I now clean the filter with dish
detergent soak and thorough rinse to reuse for three cycles, maybe =
20-25lbs
per cycle, then replace with a new one and repeat the clean and reuse
cycling.  The small perforated one on top doesn't seem to have as great =
an
impact on the airflow or resulting temps encountered as the plastic main
filter in front of the fan does.  I have only replaced it once and am
questioning it's necessity as I roast outside anyway.
Good luck and happy roasts, 
Mark
