Low pressure on milk frother on breville coffee machine
First,I'm NOT a Breville tech, but this is a very common problem with steam boilers. Your valve seal(s) are worn and needs replacement. Any leaking water or steaming from various places other than the steam tip is causing your tank to lose pressure. The heater needs to stay on longer just to keep everything up to pressure and properly heated. You probably noticed that your shots may not have the creme or very thin and watery. Milk steaming takes a long time or not enough steam to complete a froth, especially on a Latte. Your machine needs servicing. Contact your vendor or MFR for service.
** loose steam wands will fall off and be re-assembled without the ball seal or washer. Look around the machine for a round disk made of hard rubber or nylon plastic. Take apart the wand and reassemble with the washer or get a new washer and tighten,.
** other places were you can loose steam pressure is the Anti-siphon valve, Safety valve, and various pipe fittings to the steam boiler. Look for steaming plumes from unexpected areas of the machine.
** Scale that has built up to the point of causing valve problems are usually too much for DE-scaling to work properly. Usually done as a preventive maintenance rather an alternate to repair. Like a blood clot, if you remove it while still in an active system. Where does this clog end up? This debris needs to be physically removed from the pipes, valves, and/or tank. Heavy scaling is a sign of an old machine that will need a lot of servicing to bring it up to MFR specifications.
** Final; The steam wand(s) are the most used (and abused) parts of the machine. Constant cleaning is a required task that needs very diligent baristas to keep it fully functional. I've found that best operators use the following method to keep the steam wand in top condition; Remove milk froth pitcher completely from wand, Send a short blast of steam to clear milk residue from tip. Take a damp towel to grab wand an pull downward to wipe off any remaining milk residue. Leave the wand in a pitcher of cool water to soak during long break periods to help break up any dried milk. Let soak over nite when not in use. Have your operators notify you of any 'loosey-goosey" wands. Tighten them properly but make sure all the parts and washers are there. Check your manual or just ask your technician to show you the next time.
