Cat water fountains · Choose by your needs
If dishwasher permission for the supplied drinking surface is essential, PetSafe HydroSphere Cordless documents top-rack washing for its bowl, tray and splash guard; Catit PIXI Steel #43720 permits its removable steel top; PetSafe Viva's exact plastic tray is also top-rack safe. Do not extend any of those permissions to the pump, adapter or electrical base.

| Model | Exact model | Part the source permits | Separate care requirement |
|---|---|---|---|
| PetSafe HydroSphere Cordless 60 oz PWW00-18313 Black / PWW00-18311 White | PetSafe HydroSphere Cordless | Bowl, steel tray and guard: top rack | Pump is disassembled and hand-washed; base is not waterproof. |
| Catit PIXI Fountain with Stainless Steel Top 43720 | Catit PIXI Steel #43720 | Removable steel top only | Plastic body/tank and submerged electrical pump need separate care. |
| PetSafe Viva 140 oz Plastic PWW00-17922 140 oz plastic | PetSafe Viva 140 oz Plastic PWW00-17922 | Exact bowl, pump housing and tray: top rack | Pump is opened and hand-cleaned; adapter stays out. |
Choose it when: The exact HydroSphere Cordless cleaning instructions name the bowl, splash guard and tray as top-rack-safe components.
The limit: The pump requires hand washing and the base must stay dry; dishwasher suitability does not cover the electrical assembly. Battery mode is motion-triggered, not continuous.
Choose it when: The exact North American #43720 guide permits the supplied stainless-steel drinking top in a dishwasher.
The limit: The permission is limited to that removable top; it does not make the body or pump dishwasher-safe. Its 2 L setup is outlet-powered.
Choose it when: The exact 140 oz selected Viva configuration and U.S. care sources permit top-rack cleaning for the specified plastic surface/bowl parts.
The limit: The pump still needs manual disassembly and the adapter must remain outside the dishwasher. Its 140 oz capacity is nominal and does not establish a refill interval.
This is a broad all-material answer. Some sources permit a separable surface or selected non-electrical fountain parts; the named part differs by model. Read the exact manual before putting a component in a machine, and follow any stricter instruction when a product page and guide conflict.
Do not put a pump, cable, transformer or base in a dishwasher. If you also require a particular surface material, use the matching material answer and keep the surface and dishwasher checks together.
No. Catit #43720's guide names the removable steel top; the body and electrical parts are separate.
No. The exact instructions require disassembling and hand-washing the pump, while the bowl, tray and splash guard are top-rack safe. The base is not waterproof.
Treat permission as unconfirmed until the manufacturer resolves the exact component conflict. For example, supplied Dockstream 2 evidence conflicts on dishwasher use, so it does not meet a strict confirmed-permission condition.
