Ignore Dave, he's trolling. It's definitely not normal.
Another theory might be scale buildup, which would effectively reduce
the volume of the boiler. Maybe try descaling?

Thank you for the responses Ira and Ken! I'm not sure if you are
saying this is normal Dave? The steam boiler is on as I do not have
the version where you can operate them independently. However, during
the summer I generally make iced coffee and did not use the steam
boiler at all here. I have the machine on a timer in the morning so
it has over an hour to heat-up before I use it. so it should be plenty
hot and the steam boiler should be more than ready and holding
temperature by then. So certainly an interesting clue that the steam
boiler light comes on. I wish I had a switch to deactivate the steam
boiler - maybe one could be retrofitted - would save a lot of time and
energy in the summer though we are just about back to the hot coffee
season anyway. If there is a steam leak I wonder if I can 'see' where
it is leaking if I take the shell off the machine - I will try to do
that this weekend and see what it looks like in there. The steam leak
theory might also explain why it kind of bottoms out and hangs out at
197/198 for awhile and then quickly climbs back to 202 once it gets
going. Kind of like the initial heat-up phase where the steam boiler
is on for awhile then the brew boiler takes over and climbs quickly
until it cycles back to the steam boiler. Let me know if anyone
thinks of anything else to try - appreciate the responses and ideas.
Thank you very much,
Jarad

I wonder if you have a steam leak? See if your steam pressure
starts to drop quickly after you switch off the steam switch. In
the video I noticed the steam heater light was on while you were
pulling the shot. The PID can't send power to both heating
elements at the same time on 110 volts. But yea, something is
wrong. Mine never drops that fast. Not even close. But I noticed
as soon as the steam light went out the temp started to recover.

I have a Brewtus 3 (pump version) with PID that I bought at
the end of 2009 that I haven't had any problems with. However
the temperature has started dropping pretty significantly
while pulling shots. I have it set for 202 right now to
compensate for the temperature drop but it will fall from 202
to 198/197 over 20-30 seconds. I have a 90 second video I
took if anyone is interested in seeing the temperature drop
and recovery:

Curious if any ideas or suggestions on what might be happening
here and what I might need to do to get it repaired. It will
hold 202 on the PID all day - it's just when the shot is
pulled that the temperature drops. Thank you very much,
Jarad
