Diagnostics on the GLW11 show the Pressure Tube fault. Where is the Pressure Tube and how do you check it?

check the engine for an oil pressure sensor to report on low oil level
that will also put on the oil light if you have one

- Motor control module fault:
Fisher and Paykel washing machine error 1:
Primary Source: Motor control module.
Action: Replace motor control module.

3 - Motor control module fault:
Fisher and Paykel washing machine error 3:
Primary Source: Motor control module.
Action: Replace motor control module.

9 - Size setting fault:
Fisher and Paykel washing machine error 9:
Primary Source: Motor control module.
Action: Reset machine size as per service manual instructions. If fault repeats replace Motor control module.

10 - Temperature Sensor (Thermistor) Error:
Fisher and Paykel washing machine error 10:
Primary Source: Thermistor.
Action: Replace Thermistor.

11 - Pressure Sensor Fault:
Fisher and Paykel washing machine error 11:
Primary Source: Pressure Tube.
Action: 1 - Empty all water from the machine. Remove pressure tube from pressure sensor, clear pressure tube of any water and reconnect tube (blow down the tube is necessary). 2 - If fault repeats, replace Motor Control Module.

12 - Flood Protection Error:
Fisher and Paykel washing machine error 12:
Primary Source: Water Valves.
Action: If the water valves are on continuously, check that the water valves turn off mechanically by disconnecting power to the machine.
Secondary Source: Pump System.
Action: Check pump for blockage and drain hose for correct height(end not immersed in water) or kinked.
Tertiary Source: motor control module.
Action: If water valves are been driven on electrically, replace motor control module.

36 - Water Leak Fault:
Fisher and Paykel washing machine error 36:
Motor control module has needed to top up the water level more than 4 times during wash/rinse cycle. Most likely cause is waster siphoning out or the machine has developed a leak.
Primary Source: Drainage system.
Action: Check that the hose is not less than 850mm from the ground
Secondary Source: Pressure tube.
Action: Make sure the pressure tube is fitted correctly and doesnt have any holes.

37 - Blocked pump:
Fisher and Paykel washing machine error 37:
Primary Source: Drain System.
Action:
1. Check that the drain hose has not been kinked.
2. Check the length of the hose. 1m is maximum extension.
3. Check drain pump winding for open circuit.(Note: Pumps are fitted with a thermal cut out and will reset after cooling)
4. Check for physical blockage to pump and hoses.

38 - Pressure Sensor Fault(empty reading during wash cycle):
Fisher and Paykel washing machine error 38:
Primary Source: Pressure tube.
Action: Check if tube is fitted correctly, check for blockages or holes in the pressure tube.
Secondary Source: Motor Control Module
Action: Replace the module.

39 - Pressure Tube Fault:
Fisher and Paykel washing machine error 39:
Same as fault 38.

40 - Bowl Dis-engage Fault:
Fisher and Paykel washing machine error 40:
Primary Source: Mechanical.
Action:
1. Check that there are no clothes or other foreign objects preventing the clutch from re-engaging. Excessive suds can also stop the bowl rotating.
2. Check the clutch splines for physical damage.
3. Check that the pressure tube has not come off, kinked or blocked(blow down the tube.
Secondary Source: Motor Control Board.
Action: Change Board.

43 - Out Of Balance Switch Fault:
Fisher and Paykel washing machine error 43:
Motor control module has found that signal returning from the out of balance switch indicates that the switch is permanently on or the harness to it is disconnected.
Action:
1. Check the level of the machine.
2. Check wiring to the switch.
3. Check switch for continuity and corrosion.

44 - Water in Bowl During Spin:
Fisher and Paykel washing machine error 44:
Primary Source: Drain system.
Action: Check for blockages/kinks in drain hose and function of the drain pump.

48 - Hot and Cold Inlet Valve Incorrect Signal:
Fisher and Paykel washing machine error 48:
Primary Source: Wiring.
Action: Check the wiring.
Secondary Source: Inlet Valves.
Action: Check the resistance of the coils.
Tertiary Source: Motor Control Module.
Action: Change Module.

49 - Cold Water Inlet Valve Faulty:
Fisher and Paykel washing machine error 49:
Action: See fault 48.

50 - Hot Water Inlet Valve Faulty:
Fisher and Paykel washing machine error 50:
Action: See fault 48.

51 - Diverter Valve Fault:
Fisher and Paykel washing machine error 51:
Primary Source: Blocked diverter valve.
Action: Check for foreign objects in the valve.
Secondary Source: Motor Control Module & Diverter Valve
Action: Plug the machine into the power point but off at the control panel. Check voltage on the plugs at the diverter valve. If voltage around 230V, change diverter valve and motor control module

Fault code 40 info
40. (00101000) Bowl Dis-engage Fault
While carrying out a bowl check, the Motor Control Module has found that the bowl is not
engaged even though the pressure sensor indicates that the bowl is empty. The Motor
Control Module continues to check for 2 minutes, after which time it displays this fault. The
first two areas to check are the clutch and the pressure tube. If these two appear correct,
then the fault could be in the pressure sensor in the Motor Control Module.
Primary Source: Mechanical.
Action: 1) Check that there are no clothes or other foreign objects preventing
the clutch from re-engaging. Excessive suds can stop the bowl
rotating.
2) If the machine is empty of water, carry out a clutch disassembly
procedure and check the spline drive.
3) Next check that the pressure tube has not come off and that it is
not kinked.
Secondary Source: Motor Control Module.
Action: Replace Motor Control Module.

If the fan is running then the most likely cause is a bad pressure switch or disconnected tube between the fan and the pressure switch. I would recommend calling Rheem's technical support and have them walk you through the diagnostics. Unfortunately once a specific fault is found and resolved then other faults may be found. I hope this helps.

• F10 - Pressure switch not sensing correctly
• from another fixya expert try this
• Unplug the appliance and take the top off.
  
  The pressure switch should be on the left near the top.
  
  Take the thin tube attached to it off.
  
  Blow as hard as you can down the tube for as long as you can.
  
  Give the pressure switch a couple of good taps with your screwdriver handle.
  
  Refit the tube and try the machine again.

Fault code 39 is a pressure tube fault which means the the pressure tube has become blocked or kinked or has fallen off completely. Check first and make sure the pressure tube, the clear small hose running from the motor controller module to the bottom of the tub, is not blocked/kinked, not air leaks, no moisture, and properly attached to both the motor controller module and the tub. Replace the pressure if leaking or clear it if blocked or has moisture.

The pressure sensor is at fault if there's no any issue found with the pressure tube. But the pressure sensor is an integral part of the motor controller which make s replacing it as the only viable solution.

has the heater cut in?is pressure pipe blocked?

This part does not repairing!
Pressure sensor is in a before diesel particle filter in exhaust pipe

Check all conections to the coil pack, check to insure all spark plug wires are on, and make sure it is getting fire. With the engine not starting, the check engine light may not come on to produce a code for the diagnostics.

Error code F04 is indicating the pressure switch is jammed on empty.
Check the pressure switch and associated wiring , also check the control module connections, and wiring.
The pressure switch is usually located at the top left of washer, it has a small tube going nto it.
Hope this helps you with your problem.
