Roomba Charging Error 5 | Causes and Fixes

1. Battery Doc and Terminal

First of all, I connect my Roomba robot directly with the PSU adapter without the involvement of Doc. I found out that my Roomba was working perfectly and there was definitely an error in the Doc.

You must check your Doc whether it is making contact with the battery because terminals may get bent which doesn’t make the connection.


Clean up Doc Terminals and check for any obstructive thing causing the break in the connection.

  • You can take isopropyl alcohol to wash the terminals.
  • There may be some dust or dirt gathered around the metal terminals which don’t make the connection.

2. Clean up battery and Surface points to make a proper connection

  • First of all, unscrew all the screws with the help of a screwdriver.
  • Now. pull out the back cover of your Roomba device.
  • Pull out the battery carefully.
  • Now, clean its surface points with a clean cloth.
  • Tighten up all the screws and put its cover back on your device.

3. Roomba’s Electric Board issue

There are some issues that are only due to short circuits or consistent low voltage being provided to Roomba. There may be some contamination in the electric board or there may be some ceramic capacitors had soaked up some of the water. So, the board is not getting and decoding the voltage properly or the problem is due to the corrosion in the board.

First, try to heat the electric board of Roomba for a few seconds to let the board dry up. You can do it by keeping it in the oven at an optimum temperature of 200 Degree which does not melt the electric board. The front sensor may get a bit more melting but it will not create any issue.

Put your Roomba back in the Roomba. Now, test run Roomba to check whether it is making normal noise (notification sound)

4. Change the Battery

Sometimes, Roomba batteries may get overheated due to their much use in a day and no rest is provided to them. They usually have a lifespan of 1-2 years which depends on the usage and care. If they have completed their maximum charging cycles, you can’t expect to feel some impairment in their performance and they also get warm

  • First of all, you must ensure that you use genuine batteries which are recommended by Roomba and are compatible with the device.
  • Never use fake batteries because they will impair performance and will damage the device as well.
  • Change your batteries after the completion of their charging cycles.
  • If you have an old battery, you can use that to check whether it works.


5. Remove Yellow Label

When you buy a new Roomba battery, there is a yellow label that is inserted in the compartment of the battery to avoid any connection with the metal terminals which evades any charging issues.


You must ensure that you remove the yellow label before you install the battery which will help the battery points to make contact with the Roomba’s device contact points.

6. Battery Installation

If you have opened your Roomba device, then closed its cover and tightened the screws, you might have misplaced the correct position of seating of the battery.


  • Always tighten up all the screws to make sure the cover doesn’t get loose.
  • Make sure that you check battery points are in contact with Roomba metal contacts.
  • Check that there is no obstructive object within it.

  • Check that your charging cable is not cracked, melted, or burnt via short-circuit.
  • If your charging cable is faulty, replace it immediately to unknown errors such as Error 17.

8. Spring Loaded Pads

They are attached under the contact points of your power base. Sometimes, they get loosed and they are unclean. So, they don’t make the connection with the Roomba which causes the battery not to be detected by Roomba. Even if they are not in the right position, Roomba does not detect the battery.

A few drops of WD-40 or isopropyl alcohol will clean the contact points if they are unclean otherwise, you have to change the points or sprig breaks inside.
