MW511 or 512

The MW511 are 24volt solenoids.

Fault code 66 is pressure sensor is faulty
66. (01000001) Pressure Transducer Error [Ptx Frequency > 90 kHz]
Note: this supersedes Fault code 65 from V41 Motor controller code onwards.
The Motor Control module has received signals from the water level sensor (Ptx)
above normal frequency values.
Primary Source: Motor Control module
Action: Replace Motor Control module

Hi - pls check the clear tube which controls the water level is fitted correctly - often there is a small nylon inside these, be sure its not inside the caught inside the controller as it may be blocking the passage way.

The problem is with the tube - kinked or not connected - check to see it maybe something simple.

This can be checked by you as there is not much of mechanics . Make sure that the steam is generated in good quantity so that the cord gets full pressure, if not clean the base perfectly so that there is good contact -- no debris .. make sure with a air pressure or water jet the connection tube is clean and not damaged at any points, if so the steam will not flow .
Once this is established you will get good steam pressure or else the connection tubing cord needs a change.Also make sure there are no issues in the iron to block off steam.

Unplug power cord. First try to clean drain tube by removing bottom cover: uncrew two bolts on each side. clean tube and filter and pump. If it is fixed, you are done.
If problem comes back, unplug power cord as always. Remove top cover and replace water inlet valve (remember to shut off water valves both hot and cold), unplug connectors to blue switch and remove water flowmeter, blow air thru one end and then the other end to remove dirt inside white water flowmeter. If flowmeter bad, replace it.
Last thing may get bad is pressure switch which is brow color valve on the right side of machine.
Good luck

INFO:
Sound like its drawing air through the soap pick up tube.

RECOMENDATION:
Pench off soap pick up tube.

Hope this tip helps.

check cooling coil(in door unit)if there ice buil up then feel air vent if no air mean your fin block aready need to clean / air vent ok meant there have a leak .you need r22 test gauge and hose,reamer,tube cutter and flaring kit. 1)check suction pressure(big tube at out door unit) remove 2 way cap and 3 way cap valve then connect blue hose at service port 3 way valve (port locate at left or right depent on manufacturer) you will get pressure about 40-45 psi(air cond is running) then use a allen key(hexagonal wrench) to close 2 way valve(small tube or gas discharge side) wait 1-2 minute then close 3 way valve (suction tube or big tube) IMMEDIATELY SHUT OFF AIRCOND AND PLUG OUT POWER CORD (you need 2 person one at in door unit and the other at out door unit). this method is to keep remaining gas inside the compresser.Then leak check ,open 2 way valve about 90 degree hold it for 10 minute then close it .MEASURE THE PRESSURE keeep it for 5-10 minute. If the pressure indicate not same during the first time measured it meant there have a leakage, for air cond 1- 5 year the leakage will happen at the copper tubing connection and improper flaring .Then U need to clean in door and out door unit ,used a spanner or wrench to losen the copper FLARE NUT at out door unit and in door unit( inside insulation) then use pvc tape to cover all copper pipe/tube hole to prevent dirt go inside tube/pipe. Then lift up out door unit and used coil cleanner ditergent wait 5 minute then flush with water. Remove indoor front panel then disconnect out door unit cable at front panel in door unit then lift up indoor unit to disangage the hook and pull out the indoor unit, then clean the cooling coil ,cover electrical part with plastic .last step u need to cut (used cooper cutter)the copper pipe/tube FLARE NUT connection low side(big tube) and high side(small tube) in door connection and out door connection .Then u need to remove the burr from cut edge using reamer make sure metal powder not goes in Then make a flare after inserting FLARE NUT onto the copper pipes Then U can install back the unit check the low side pressure if the pressure 55-67 psi no need to charge

56. (00111000) Phase 4 to 6 - Basket Check No Valid Fault

While carrying out a basket check, the machine has not been able to determine a

valid tub status and so the Display flags this fault. This fault differs from fault 40 in

that a valid tub status could not be determined. The first two areas to check are the

clutch and pressure tube. If these two appear correct, then the fault could be with

the pressure transducer in the motor controller.

Primary Source: Mechanical.

Action:

1) Check that there are no clothes or other foreign objects preventing the clutch

from re-engaging.

2) Next check that the pressure tube has not come off and that it is not kinked.

Secondary Source: Motor Controller module. (Phase 4) Rotor Position

Sensor (Phase 5 and 6)

Action:

Replace the Motor Controller module. (Phase 4) Rotor Position Sensor (Phase 5
and 6)

check out the DRAIN MOTOR PUMP , its a small motor with 2 hoses connected to it , it could be clogged , need to remove it , inspect inside the impellers for any debri , clean it , re install and try again , hope this helpful AJ
