Time:
15-20 minutes

Parts:
99004-17001 Honeywell Transducer Assembly.

#2 Philips Head Screw Driver
1/2" Wrench

Step 1:
  1. Turn off machine and depressurize steam tank.
Step 2:
  1. Remove cup tray and rear panel to expose transducer and electronics.
  2. Unplug old transducer from board and feed it through the gap in electronics shield. 



Step 3:
  1. Use a 1/2" wrench to remove the copper line and transducer from steam tank.


Step 4:
  1. Feed the new transducer cable through the heat shield gap. Attach the Molex to the transducer port on the board.

Tighten compression fittings appropriately: Finger tight followed by a quarter turn with correct wrench. If more tightening is necessary, proceed with small incremental turns.

Step 4:
  1. Turn on machine. Verify ball valve drains are closed. 
  2. Allow autofill cycle to complete.
  3. Run water through groups to confirm brew group saturation.
  4. Allow heating cycle to complete and check for leaks once pressurized. Tighten compression fittings if needed.
