Coffee Valve Safety Kit SP0001676

I actually replaced the entire pump in my Breville Double Boiler but had to get the pump from another supplier. They're all made by the same Italian company. I also replaced the solenoid which was making a loud grinding noise when the start button was pushed which is typical when a solenoid goes bad. Both installs were fairly straight forward. Two phillips screws accessible next to the brew head are removed, then two Torx screws from the back of the machine and the top lifts off. Just be careful of the wires that go from the circuit board that is attached to the top. Lift gently so you don't break them. You can maneuver the top to lift the water access funnel from its tube, then pivot the top out of the way. Otherwise, you can remove the printed circuit holder if you want to.

The back covers are held on by phillips screws. Remove them and the two covers. This gives you access to the 4 phillips screws which hold the rubber vibration dampers that the pump sits in. Remove the two wires that plug into the pump (be sure to mark which is which) and also you'll need to desolder or cut the wire from the Thermal fuse. You can solder it back later. Disconnect the tube at the top of the pump by pulling the clip out. Be sure that the little o-ring and flat washer are not lost in the process of pulling the tube out. Check to see which order they are in the safety valve head.

I decided not to replace the entire pump since it would have required detaching the thermal fuse which is glued on the housing. I figured the problem was with the plastic pumping mechanism, not the electromagnet that drives it. It was a simple operation to take the plastic pump out of the electromagnet and swap in the new one. Once that was done, I just reversed the order and soldered the thermo fuse wire, ensuring I used a little heat clip on the wire to avoid over heating the insulation. I slid a heat shrink over it before soldering to insulate the joint.

The solenoid was easy to take out and replace. Just unplug the tube and remove the 4 phillips screws. Be careful not to damage the silicone gasket that is under the solenoid. I removed it and found quite a bit of corrosion under it. Seems they didn't do a good job of installing it in the factory and you could tell it leaked a bit and corroded the surface. I used fine emery paper to make it smooth. Also, be very careful not to drop the little metal tubes that fit into the solenoid behind the two small silicone disks. Install them, put the silicone gasket on the solenoid to keep them from dropping out then carefully put the part back and screw it down. Install the feed and overflow tubes and the wires and install the rear panels and top. Keep the rear panel screws loose until the top is placed on so that the lip of the top fits behind the top rear panel. Then tighten all the screws. After this operation, the machine worked like new. In fact, better than new. I put the pump in clean mode and it pulled 13 pounds in the cleaning cycle. The new solenoid works great. No more grinding sound when the button is pushed.

1) Unplug the power. Let the machine get cold. Remove the main top cover.
2) Detached both tubes from the uppermost safety valve . You need pliers to detach the clips.
3) Unclip the left-hand plastic cap and unscrew the threaded tube. Its in about 6 turns, which sets the pressure release. Set these aside, now the whole part can turn anti-clockwise.
4) Replace it with a new one, put it back together and reconnect the tubes.
5) Reassemble.
6) Make a coffee !

1. Make sure machine is unplugged. Remove water reservoir.
2. Remove 2 screws from back of the unit and 2 recessed screws from under the front lip. Lift top cover off. It may be tethered with a ground strap. Set it to the side of the machine. Loosen 2 captive screws from the back of the unit and set the rear cover to the side.
3. Remove retainer clip from top of safety valve and disconnect outlet tube. If o-ring remains in pressure relief valve, pick it out with a small pick or jeweler's screwdriver and save.
4. Remove clamp from side of safety valve and disconnect pressure relief tube.
5. Unscrew safety valve and remove. Set old valve aside.
6. Screw replacement safety valve onto pump outlet. Continue to turn clockwise to orient pressure relief outlet toward pressure relief tube.
7. Re-attach pressure relief tube and secure clamp.
8. If o-ring was removed from old pressure relief valve in step 2, place it on outlet tube. Insert outlet tube into top of pressure relief valve and secure with retainer clip.
9. Test machine for function. If pressure is still inadequate, pump motor may need to be cleaned, rebuilt, or replaced.
10. Replace rear and top covers.
