On a Rainbow, the water pan is not an accessory. It is the filter. A cracked, chipped or badly clouded basin takes the whole machine out of service, which is why this is an urgent-need part rather than a maintenance item. This is the genuine Rexair 2.5 quart basin for the Rainbow E and E2 series, the same clear pan the machine was built around.
Rainbow owners tend to be long-term owners. These are machines people keep fifteen to twenty-five years, and the pan is one of the few parts that fails outright rather than wearing gradually. It usually goes from a drop, or from cloudiness and brittleness after unapproved fragrances or essential oils have been run in the water. Buying a second pan is also common practice, so one can air dry while the other is in use.
Use cases
- Direct replacement for a cracked, chipped, clouded or stained basin
- Second pan so one air dries while the other stays in service
- Restoring a Rainbow that is otherwise sound but unusable without a sealed basin
- Vacuum repair shops servicing Rainbow water filtration machines
Field notes
Owners typically fill to about half an inch above the dome and get roughly an hour of cleaning before the water needs changing, dumping and refilling every twenty to thirty minutes on a whole-house clean. The clear pan is what makes that judgement easy, since water color and the change in sound both signal when it is time.
Do not pour the dirty water down a household drain or into a septic system. The grit and carpet fibers accumulate in the pipes over time, and experienced owners either dump it outdoors or strain it first. Rinse and dry the pan after each use, and store the machine off the basin so trapped humidity does not sit inside the unit.

Frequently asked questions
What size is this pan and what does it fit?
It is the 2.5 quart basin, and it fits the Rainbow E2 Type 12 in Black, Silver and Gold series as well as the Rainbow E-2 e SERIES.
Is there a larger pan available?
Yes. Four quart basins exist for these machines, which some owners prefer for heavy pickup or shampooing because the pan needs dumping less often.
Can I put the water pan in the dishwasher?
No. Hand wash it with mild soap and warm water. Dishwasher heat can warp or damage the plastic.
Why did my old pan crack?
The usual causes are impact from a drop, or the use of fragrances and essential oils that are not approved for the machine, which can make the plastic brittle, cloudy or stained over time.
Should I store the machine sitting on the water pan?
No. Storing the unit on the basin traps humidity inside, which encourages corrosion and mold and shortens motor life. Empty, rinse and dry the pan after each use.
Discount Cleaning Products supplies genuine Rexair parts rather than aftermarket substitutes, because on a water filtration machine a poorly molded basin is a leak waiting to happen. Our US-based team can confirm which basin your Rainbow takes if you send us the model and series from the machine.
