What to do if the bellows will not fill.
Check the following:
- Ensure that the ON/OFF valve on valve block is in the "ON" position.
- Check that Speed Control Knob is turned to a full open position.
- Make sure screen/filter is free from rust, corrosion , or any restrictions
- Make sure the pilot valve stem has made contact with the shut off rod. The valve stem has to be shifted to the far right in order for the bellows to fill.
- With the stem in the far right position there should be no pressure in the line running from the top of the pilot valve to the front port of the valve block. To check for pressure turn water supply off. Remove plastic line that runs from top of pilot valve at the point where it is connected to the front of the valve block. Carefully turn the water back on and with the pilot valve stem shifted to the far right, there should be no water coming through the line. If line is pressurized the pilot valve is bad or is plumbed incorrectly.
- Carefully open the drain valve in the tee coming from the Bellows. If there is a good flow of pressurized water coming out of this drain, then the line to the bellows is clogged.
- If your unit is equipped with a quick exhaust valve, check to see if water is running through it. If water is running through the quick exhaust valve and not filling the bellows, the quick exhaust valve needs to be replaced.

What to do if the bellows will fill but will not exhaust
Check the following:
- Check for obstructions or kinks in the exhaust drain line
- Make sure the pilot valve stem has made full contact with the pawl adjustment plate. The valve stem has to be shifted to the far left in order for the bellows to exhaust.
- With the pilot valve stem shifted to the left, the line from the top of the pilot valve to the front port of the valve block should have pressurized water in it.
- To check for pressure, turn water supply off. Remove plastic line that runs from top of pilot valve at the point where it is connected to the front of the valve block. Carefully turn the water back on and with the pilot valve stem shifted to the far left, there should be water coming through the line. If line is not pressurized, the pilot valve is bad or plumbed incorrectly.
- If the pilot valve is working correctly, the valve block or the quick exhaust valve may need to be replaced or repaired.
- On rare occasions, the bellows has been known to accumulate sand from the water supply causing the bellows to be unable to collapse.

What to do if the bellows cycles but the spool will not wind in the tube
Check the following:
- Note: First check to ensure that the drive pawl is dropping into the slots on the spool ring.
- Is the hold out rod lowered into the run position?
- Is the hold out rod deformed so that it cannot be lowered enough?
- Check that the drive pawl moves freely (oil, grease).
- Is the drive pawl broken?
- Has the drive arm moved on the spool so the drive pawl will not engage the slots in the spool ring?

What to do if the drive pawl moves spool ahead but spool rolls back with pawl as bellows exhausts
Check the following:
