McCulloch FHH18A - Wash Machine Hand Assembly leak

When I set up pressure washer and make sure of water flow, etc. I then turn on the electric. The Wash Machine Hand Trigger starts spraying out water out the sides in addition to shooting a stream of water out of the end of the trigger. What would cause the trigger to stream water out the side of the trigger?

I had a Karcher water sprayer that did the same thing , the repair man told me it could be repaired IF he could get parts , guess what, he COULDNT get parts so i had to buy another one , the answer to your question is yes they can be fixed provided you take it somewhere that can get parts . hope this helps

ps i could have fixed it myself with the right part, its not a hard job to strip it and rebuild it

I assume you mean the rubber O rings inside the wand. I had to replace mine as well. I had to visit several plumbing supply stores to find one that fit. I ended up taking the end of the wand with me so I could make sure the O ring fit. The ring you are after is a number 5, but you need to make sure it is thick enough to make a good seal.

SOURCE: I have a McCulloch FHH18A

I would guess there is a leak somewhere inside the unit that is spraying water on some electrical component and causing a ground fault.

Trigger don't release


I have a hose and gun that fits the McCulloch FHH18A that I no longer need as I had to buy a complete universal hose/gun and wand unit since I had broke the wand and the replacement wand was no longer available. If you are interested in it, email me at burmakow@nwciowa.edu and we can figure out a price.

They are probably not allen head screws but rather tamper proof Torx screws. You can break out the small pin or you can now buy special Torx bits with holes to remove tamper proof screws. They should be available at most hardware outlets or at shops that sell Chinese imports. Torx bits are prefixed with a "T" and the size you are looking for is probably about a T20, but the sets come with an assortment of sizes up to about T40.

If the pump is leaking then it is going to either be the water seals or o-rings on the inside of the pump. If this is the case I would recommend just tossing the unit, what it would cost to rip the machine apart and replace these items would be more than what the machine is worth.
