Hisense Dishwasher.

The top basket sprayer for the utensil rack fell off after it completely wore through the thin plastic ring that held it in place.  It is so thin, it looks designed to fail.  I could not find this part on offer.  Appliance repair places only offered the full assembly, which was pricey and excessive.

So I designed a new one.

The white part is held in by a coarse threaded T20 screw.  It requires unclipping and pulling down the flat channel from the top of the dishwasher unit to unscrew.  The sprayer assembly itself is easy enough to pull apart with some plastic cards at each of the contact points.

To install the part:

  1. Take the replacement axis and insert it into the top half of the sprayer arm assembly.

  2. Line it up with the attachment ring within the channel at the top of the dishwasher.  This will fit around the ring and require lining up with the two notches.

  3. Screw in the T20 screw.  Do not overtighten.

  4. Snap on the lower half of the sprayer assembly.

Some notes:

I designed this part with printing from Polyamide (PA/Nylon) in mind.  PA loves water.  It becomes tougher and more flexible.  But it also expands, by a lot.  I made clearances to account for this expansion, so the part may seem undersized when first installed.  Polypropylene may be another good option for this kind of application as I think most of the plastic parts in the dishwasher are PP.

Disclosure: The PA part I have been using daily for over 7 months did fail.

Update:    I uploaded a version with a thicker disk (v1.1).  I am also going to anneal the part for 10-12 hours before I install it.  I will post an update after some time.
