I presume the Brewtus is in your kitchen.  Unless changed, I believe the NC 
electrical code requires 20 amp breakers in kitchens.  15 amp receptacles are 
allowed since there are usually multiples on each circuit, but for me, I would 
stay with the 20 on a large load.

Things aren't going so well with our Brewtus II - Katherine was making our 
morning shots, and as she turned towards the sink with its drip tray: "There 
was this 'Swizz. Pop., BANG!' and all the kitchen lights went out."

 

No, it wasn't our neighbors playing with an RPG - it was the blessed brew 
boiler heating element going South and taking out a GFCI socket in a fairly 
spectacular fashion:

It looks like there was water intrusion near the element's base, and when it 
flashed to steam it ripped the element apart. The loud bang was a very marginal 
GFCI socket failing to deal with a dead short on a twenty amp circuit.

 

The circuit is now on a 15 amp breaker, there's a medical-grade dual socket 
rated for 15 amp continuous service, and a new boiler element is due this week 
from WLL.

 

No one appears to have stock on the Expobar-specific thread sealant - Stefano 
recommends an italian sealant which looks very good - which I'd buy, but USPS 
from Oregon to North Carolina is pretty glacial at the best of times, and we're 
getting impatient.

 

The local HVAC folks who keep our 75 year old steam heat system working swear 
by Permatex 56521: "It applies easily, sets up quickly, remains flexible, and 
in a clean joint - never, ever leaks." 

 

56521 has no NSF rating, and its MDS lists ethanol as a primary carrier, with 
1% Methanol as an additional carrier. While folks have maintained that K's 
coffee: "Could stun a horse & blind a donkey..." I've no desire to actualize 
their experience, and will use the sealant only on the the upper threads with 
4-5 wraps of teflon tape on the lower threads to isolate it from the brew water.

 

There appears to be good water flow through the E61, with no portafilter the 
Elka pump will fill an 8 oz glass in less than 15 seconds - I'll pull the water 
level probe, clean and inspect it for continuity and scale, to eliminate it 
causing an underfill condition.

 

Much past this point, my troubleshooting gets fairly mystical, since the volume 
of water flow through the grouphead belies issues with the parker valve or Elka 
pump, my most popular theories tend to include demons, Maxwell Houses, and 
extremely bad JuJu.

 

Cheers & Thanks

Jim
