Can you put a hot tub filter in the dishwasher or use a pressure washer?
By MySpaFilter Editorial Team · Last reviewed
No to the dishwasher: Jacuzzi says dishwashers and washing machines aren’t recommended because high heat and aggressive spray can warp end caps and don’t clean deep between the pleats[10]. For rinsing, use a garden hose; Jacuzzi says to avoid pressure washers that can tear fibers[10].
Quick answers
| Method | Verdict |
|---|---|
| Dishwasher / washing machine | Not recommended[10] |
| Pressure washer | Avoid — can tear fibers or damage seams[10] |
| Garden hose, top-down at ~45° | Recommended[4][1] |
| Stiff brush | Never on the media[1] |
| Dishwasher detergent as a bucket soak | Allowed by Unicel/Pleatco (1 cup per 5 gal)[4][1] |
Note the difference: putting dishwasher detergent in a soaking bucket is a published option; running the cartridge through a dishwasher is not. Sundance’s 2024 680 manual specifies a high-pressure hose nozzle for its outer pleated filter but a low-pressure nozzle and no chemicals for the insert[11] — follow your own spa’s manual.
