HWH 625 series levelling jack electromagnet.

[31dh]

I took the electromagnet out to replace the O-ring because it was leaking And now I cannot get it back in. It screws on the internal threads but before the exterior threads start the electromagnetic tips up a little bit and will not go in the hole.
In the picture that I attached it shows something orange inside and we were wondering if that is stopping it from going back in.
We are wondering if we took the plug out just above it (which a 5/8 wrench fits) if that
would enable us to pull that valve out of there and then be able to rectify the problem?
Any suggestions would be greatly appreciated.

I have the HWH 625 system and I've done a bit of work on it but for the life of me, I have no idea where in the system you're working on and or, what that item you're speaking of is.

I believe what you have done is to remove one of the 4 solenoid that control the jacks. I’m guessing here but it looks like you have removed the left rear solenoid and the front section of the solenoid has unscresed from the front of the (now removed) solenoid.

The way to fix this is to remove the hose from the opposite side of the manifold. If you look on the opposite side of the manifold, where that stuck part is, you will see the jack hose. Remove it and using any piece of metal (like a ground off point nail, or a long punch and insert it from the hose side. Gently tap on it and I guarantee that part will come out.

I had the same problem with my 625 system and a support person inside HWH told me what to do.
Feedback to the rest of the group will help them as well.

Thanks guys for the info
I called Paul (602)-549-3638 (Skip suggested)
Paul suggested to screw the electromagnet on to the valve only far enough so that the electromagnetic thread does not start threading then pry on it and it will pull the valve which we did.
The problem is that somewhere along the line it got cross threaded that’s why we could not get it back in.
So we figured out what tap we needed which is M 20 x 1.5 . tried around locally and found one for $150 which we found excessive so I ordered it on Amazon for $50 and it was here in two days
Thanks again Glen

i tried that 928 number and he dont answer. really, its a number is use for data alone on my computer. the 602 549 3638 is a good number.
i made a tool that works for the extraction of that part. i will post it tomorrow. its just a coupler and a long bolt. it threads onto the piece stuck inside.

I took an old solenoid that had failed, and ground the threads off of it, and use it to extract the part that stays on the manifold.

Ok,
One more time, WHAT is the “electromagnet” you’re referring to?

Yup, me too. HWH 625 series service manual


FWIW, this thread is the only search result returned for "HWH electromagnet" on the internet.

I don't know the HWH system but it's possible the OP is asking about a magnetic reed type switch the jack may contain.

That is a depressingly familiar sight. It looks like one of the solenoid valve ends screwed into the manifold. The HWH solenoid valves comprise a solenoid and a valve that are threaded together. Sometimes, when you unscrew the solenoid valve, the two parts separate. The solenoid comes off and leaves the valve end inside the manifold.

A solenoid is a specific type of electromagnet, one having a plunger inside a tubular coil wound around an inner sleeve. When the coil is energized the plunger, made of a magnetic material (e.g., steel) is drawn into the sleeve on the inside of the coil.

While the OP might not be using term everyone recognizes, or the one in the HWH manuals, the term itself is actually correct. It is, in fact, an electromagnet.

Yep! Reed Switch

OK, thanks for the explanation and edification. We'll stick with what HWH calls it for simplicity; a solenoid.
Thankfully 31 has his problem corrected and ended this thread.

That's certainly what I call it.
