WM-5 Hobart Rebuilt Pictures

[bobbins]

I finally taken some pictures of my (PRE-1985) Hobart WM-5 Dishwasher. This model has a built in booster, 208/1/60. I just tested the motor and it seems to work great!. The only problem I have is replacing the tub gasket....I have a new Hobart door gasket (thanks to Ebay). Does anyone have any experience installing these gaskets?

I will post my SR24 Hobart in the Deluxe forum. I am hoping to get it installed later tonight

Interior picture - Hydrosweep - for some reason the tips hit the fill inlet - I will need to bend the tips

What do you mean ???

"The tips of the Hydro Sweep hit the fill inlet" ?
Are you talking about the Overflow Cover in the front left hand side of the machine ? You shouldn't have to bend anything. Just make sure that overflow guard is seated securely. But honestly,WM5's these days are vague to me.

WM5?

With what series of residential machine does this corrospond?

I have some limited familiarity with the 21 series machines, but the stainless interior is very interesting.

I was talking to someone that if a domestic Hydro Sweep was used, the tips of the spray arm may touch the white fill inlet under the dishrack support. I looked at a WM-5 at a coffee shop and noticed the tip were bent on theirs....

mine does too

I have a wm-5h and one of the tips of the wash arm has always hit the plastic part of the water inlet. no big deal, just a few more rythmic sounds. You could bend the tips a little or maybe file down some of the plastic on the water inlet. I have put the wash arm from a KSD-18 in mine since my origial was worn a litte and get more pressure. Do you have the wear washer on top of the wash arm support? If you take a look at the various models of the wm5 series at hobart you will see that some of the different models have a different fill assemblies.
your dishwasher is very nice. Mine is a ml - 33997. I have replaced the motor, pump housing, timer, booster element and welded the back corner of the booster tank since I have had it. Haven't had to replace the door seal but someday will have to. Have also put a toggle switch in line to the power to the timer so I can stop the cycle at any point getting a longer wash, more fill on the purge letting me get 2 full rinses, or a longer final rinse. Just don't stop it while it is filling if you are not using the overflow drain assembly. Since I do not have a floor drain, I have the drain connected to the sink drains and the overflow assembly sealed off.
Good luck with your restore.

back to the future!

These WM5 series machines were based on the KitchenAid 18 series but for the European market. They looked just like the machine in the pictures, but with the double racks and wash arms, the constant rinse assembly on top as well. But they were also equipped with water softeners as were most machines in the European markets.
Where you see the overflow in the pictures, there was a pressure switch to prevent the sump heater from coming on unless there was the proper level of water in the tank as well as overfill protection.
Some of the earlier models of the WM5's came with float switches when a pumped drain was used. They were discontinued when they were found to be clogging up with grease and such and proved to be unreliable. That was remedied by using dual fill valves and a flow restrictor in the fill line and the hole in the tank was capped off.

For the record, the SR24, which replaced the WM5 after the LX series came out, used a float and reed switch similar to what Hobart uses in all their other machines.

Also, take notice that there are indentations in the door where the rinse agent dispenser and detergent dispensers would go in the domestic models.

The European commercial units had dispensers mounted on the sides of the tank and filled thru caps on the inside of where the door closes. These were not used on this side of the pond.

The standard hydrosweep DOES NOT fit these machines as the ends of them will hit the fill assembly as noted here. They came with the tips bent from the factory to avoid that from happening and to prevent the arm from hitting the back of the tank which is curved out at the bottom. Once again, you can get the proper arm from any Hobart office if you want to pay the price for it. That style replaced all the arms used in earlier machines.
