I finally called WLL and they said that the fact that it went up to 9 bar steady with blind portafilter suggested that pump was OK and the problem might be in a restricted input. They were still out of stock in the required tubing that should have been included with the new pump kit that I had received.
I ordered 4mm x 6 mm silicone tubing from Amazon. $5 for 10 feet. I replaced the input tubing to the pump. PROBLEM SOLVED. I tested by pulling 4 shots over 2 days. the brew pressure is now steady. Bonus: the Brewtus is now quiet all the time when not pulling shots. Another symptom of the restricted water input line was that the Brewtus pump had been cycling on for a few seconds a few times an hour. It is quiet now. -- You received this message because you are subscribed to the Google Groups "Brewtus" group.
