Well, the only casualty in our house from the superstorm may be our Roomba 533. Basement flooded and the old gal was sitting in a few inches of water for an hour. I’ve dried her out (though not inspected the inside) and now she spins in a clockwise circle. The front bumper works and she backups up a few inches and then proceeds in the same clockwise fashion?
Thoughts?
I’ve searched around but does this model not have a diagnostic mode? Pet series 533
Thanks!
Christopher
Although, by holding the spot and dock button while quickly pressing CLEAN and waiting… I do get the ascending notes. But no diagnostic mode? Maybe a clue?
in auto diagnostic mode now…
Could you post a link as to what I should expect during this tests?
I am attempting to interpolate from this page but not sure what relates.
in auto mode (3 pulses) I’m never advancing past test one…
In manual mode, how do I proceed to next test?
Thanks!
Christopher
I can conclude that the right wheel doesn’t spin. From what I can tell, the rest of the test seemed to be okay?
Do you have a link for what I should expect from each test? I was interpolating from this page.

if it is the right wheel… what is the next step?
Thanks for your help!
Christopher
Perfect… I will place an order for a wheel module soon. Although the wheel spins freely by hand it isn’t getting power. A new module should fix this?
Perfect… good start. I’ll pull the trigger and order a module soon!
In the event it is not the wheel module, can I return it for a refund as I assume the next purchase will be a motherboard?
The wheel module worked perfectly! Thanks for all the help! I hope the Roomba doesn’t break again but when it does I will be back!
Hello - I have a similar issue. My Roomba 560 got wet and the right wheel is not spinning. Though mine got wet from the top after bumping into the dogs raised water bowl 
. I took it apart and dried it off. The board did have a few drops of water on it. Everything seems to be working well minus the right wheel. Any advice on whether to start by replacing with a new board or wheel? Many thanks!
My Roomba 560 also got wet. Just replaced a motherboard. Works fine now. The old one got just a tad wet while trying to clean the Roomba. I am now trying to fix the original motherboard in my spare time. Not easy to do. There are a dozen plus discrete transistors on the board all capable of toasting themselves on exposure to water.
Thanks cowolter, I think the board short makes the most sense. I will look on ebay to order a new one and try replacing it. I won’t be repairing the old one myself. Thanks again.
It sounds like one of the wheels may not be turning. In this case, the problem could be with the wheel module which would be an easy fix or with the motherboard itself.
The motherboard is on top of the robot, so it is possible that it did not get touched.

(will erase schedule too)
Hold SPOT and DOCK at least 10 seconds
If you would like to know if the wheels are turning, you can simply enter the Demo mode where Roomba lets you know it’s features.
Holding the Spot and Dock will reset your Roomba but, will not make in enter diagnostics mode. It is probably the reset tune that you are hearing.
Please let us know the outcome.
The provided link is a good source for what to expect from each test.
We do suggest to start by replacing the wheel module. We sell the module both new and used here.
It is very easy to replace by following our repair guide.
The water may have damaged the motor on the module or the motherboard. We suggest starting with a wheel module but, the problem could come from the motherboard that is not supplying power to the wheel module.
Yes. You have 30 days to return the product for refund and 90 days to return it for an exchange for another product or for an in-store credit.
Glad to hear that the replacement wheel module worked and that your robot is back to life!
We’ll be here to help when you need it.
