PRESSURE GAUGE EM6910 EM6910R

"Remove rear door, remove top long screw holding side pane and two screws at bottom. unscrew gauge pipe fitting to main pressure body and remove gauge from front by undoing two holding screws...to fit reverse procedure."

"I used this thread httpcoffeesnobs.com.aubrewing-equipment-midrange-500-150030308-replacing-pressure-gauge-em6910.html note the post at the end - my gauge came with no fibre washer so i had to source some separately from an auto spares store."

"The hardest part was trying to figure out how to remove the gauge but once you work it out it is fairly easy. remove the rear door where the water container is by taking screw out wt the bottom then remove the 2 panels 1 plastic 4 screws and 1 stainless steel 1 screw from rear at top and 2 from underneath. there are 2 nuts that hold the gauge to a bracket which in turn are attached to the front panel of the machine. the next thing is to undo the nut at the end of the tubing it is a bit tight but it can be done. then to fit the new one just reverse the procedure remembering to refit the collar to the front of the gauge as i forgot so had to redo everthing."

"Steam pump replacement reasonably straightforward - replaced pressure gauge at same time as was not working. suspected blocked pressure relief valve but changed out while machine was apart. group collar replacement requires complete disassembly as most of the 5 retaining bolts will shear at the head not allow enough movement to lift clear thermoblock clear. if this is the case pipework will have to be disconnected at the most accessable point. be aware brass elbow fittings become brittle under heat particularly at the top of the stem thermochamber. i suspect they may be british parallel pipe thread or similar so may be tricky to find. i reassembled collar using dry graphite powder on threads to try and avoid shearing bolts come the next collar change (seems to be around 4 years or so). pcb was purchased in case my suspicion about the pump was wrong so now have a spare."

"Fairly straightforward - remove and replace. a little on the fiddley side thats all."
