Didn't Pomona make some Probes for Fluke?

They do.
I think they make high quality products.
Their probe that has the interchangeable tips us the 'banana plug' style arrangement on which one slides on different tips.
 
From my perspective, the expanded metal gets weak over time and the tips dont maintain contact very well. One can always bend the metal back out and this lasts for some time, the metal has weakened and the probe tip doesn't stay on very long. One can repeat the cycle but each iteration results in a decrease in time the probe tip is securely attached to the lead.

I wanted the screw-on tips. (I think Simpson promoted this style).

Thanks to all of you. I by passed the switches as suggested, but the code only cleared when i pushed the alternative release bar further. This is an indication that the solenoid inside the door switch mechanism is not working. Further diagnostics shows that the coil is ok but its not receiving power. Another problem detected was the valve for the inlet water does not energize ( receives no power)to let water in even though i set the solenoid to its working position (the error displayed now is 4E)I wish i can get schematic to trace the power to both the water inlet valve and the door solenoid.
Thank you all once again.

I don't know if this will help but my GE front load washer had the
same problem. It turned out that the door latch assembly had several
contacts in it and that water leaking into the latch assembly from a
torn door gasket had deposited a soap film on the contacts. I replaced
the gasket and took apart the door latch assembly, cleaned all the
contacts, and returned it to service. Then everything worked. The
washer would not fill with water nor would the latch solenoid engage
if any of the door latch contacts were not making contact when they
were supposed to.
