Delta Shopmaster/ DeVilbiss Pressure Washers

If you were unfortunate enough to have purchased a Delta brand “Shopmaster” model or Devilbiss 5 or 5.5 h.p. Honda powered pressure washer, you have or WILL experience a loss of pressure at some point. There are several models that used the same pumps, but the affected machines will have a plastic shroud or cover around the entire pump area. These machines were sold by Home Depot, and maybe some other “Big Box” stores. The bad news is that there are NO REPAIR PARTS available for these units. The pump cannot be fixed in any way. Also, the engine shafts on these Hondas were cut down by Honda at the request of the pressure washer manufacturers so that there is no other application that these engines can be used for (i.e. a go cart, log splitter, lawn mower, etc.). The only thing that you can do with these units that makes sense is to put a different brand pump on them. We have available a replacement pump made by Giant that is much better quality than the OEM pump and has replacement parts available. These are $225 plus S & H.

    I think I have one of these DeVilbiss pressure washers. If I have a plastic shroud over the pump, is it one of these models for sure? I have lost all pressure in this unit, but it is only 2 years old and I have only used it maybe 3 times. Assuming that I do in fact have one of these pressure washers, could this pump have failed already? I really don’t want to sink another $225 into this machine already….if at all! Thanks, Randy.

    Randy,
    Yes, as far as I know, if your unit has a shroud over the pump, then it IS one of these affected units. We have probably seen 200 of these units in our shop for service over the years and quite often, they have very few hours on them. As an alternative to replacing the pump, we sell complete reconditioned Karcher units with hose, gun and wand for $300-$329, depending on the engine. Sorry, but there are just no easy (or inexpensive) solutions to this problem. Thank you for posting! Jerry.
