My Steam Boiler Is Not Heating/Not Steaming and No Hot Water At All

If the steam boiler in your Profitec Pro 600 is not heating and wonโ€™t produce steam or hot water, your high limit switch may need to be reset or replaced. Refer to the instructions below to confirm if this is the cause of your heating issues and how to correct it.

Confirm that water is coming through the group head when the lever is lifted, and that this has been isolated to a steam boiler issue. (You can still get water out of the group head without the boiler being full.We should be making sure the autofill function has successfully filled the boiler. Easiest way, remove the probe from the autofill and let it run for a few seconds, watching the level in the tank and see if it starts to drop. Put probe back on. Do not run this for too long or you will over fill the boiler and water will pour from the safety.

1. Is the steam boiler turned โ€œONโ€?

  • No. Turn on the steam boiler through the menu in the PID, and wait half an hour to see if the steam boiler will heat.
  • Yes. Move on to the next question.

2. Is the PID coming on on the front of the machine?

  • No.
    • Is the machine plugged in and the power switch on?
      • Yes. Move on to the next question
      • No. Plug the machine in and turn the power switch on
    • Visually inspect the high limit switch.
      • Is it melted or broken? Replace it.
      • If it is not broken, unplug the machine, and reset it.
        • Power the machine on see if it heats
      • Test the high limit switch for continuity.
        • Does it have continuity?
          • Yes. Move on to the next question.
          • No. Replace the high limit switch.

    • Is the solenoid valve (also called the auto fill valve) clicking, but not filling the boiler?
      • Clean the autofill valve.
  • YES.
    • Power down the machine and unplug it. Remove the machine to access the inside of the machine. remove the water reservoir. There are four 2.5mm screws holding down the top panel; two in the back corners, and two in the front corners. Remove these screws and take the top off, setting it aside, face up, so as to not scratch the paneling. The left side panel is held in by four 3mm bolts. These bolts need only to be loosened, and do not have to be completely taken out. Look towards the back of the machine where the side panel and the rear panel meet; there is a 3mm screw there. Loosen it.

Follow the side panel to the front of the machine and you will find the second 3mm. It will be holding the side panel to the frame of the machine, loosen this until you can wiggle the side panel back and forth by hand. Next you can lay down a towel or a pad and rest the machine on its side. You will see the last two 3mm bolts on the underside of the machine that hold the panel. Remove these two bolts. Supporting the now loosened panel with your hand, you can flip the machine upright. Take the bottom of the panel and move it outward a bit away from the machine, slightly push back on the upper left corner of the back panel to separate it from the side panel. The last bolt holding it in place is the front bolt. This is sitting in a little channel within the frame. If you loosened it enough, you should be able to slide the panel down and then push towards the back of the machine, and the panel will come right off. Sometimes, if the bolt is not loose enough or if there are imperfections from manufacturing, the bolt can get hung up. You can take your hand and lightly tape down on the upper corner closest to you, and then lightly tap it towards the back of the machine to slide it out of the channel in the frame it rests in. To preserve the cosmetics of the side-panel, be sure to rest it either on a towel or chrome-side facing upward. Three wires are connected to the bottom plate of the steam boiler: two leads and the ground wire. Unplug the leads, and leave them unplugged. Plug the machine in and turn it on.

  • Is there continuity?
  • No. Replace the heating element. Also take note that a bad element can still have continuity so an element should not be dismissed if it has continuity.
