You don’t have to call it quits and buy a new coffee maker immediately if this happens. Try troubleshooting your K-Slim first and see if you can get it to run back again.

Check Your Power Source
Since you most likely always use the outlets in your kitchen, it might not cross your mind that the power outlet might be the reason why your Keurig K-Slim is not turning on after descaling. Before you panic, unplug the K-Slim’s power cord and wait for about 5 to 10 minutes before plugging it in again.
After 5 to 10 minutes have passed, plug the K-Slim and press the power button to turn it on. If it does not work, try plugging your machine into different power sources in your kitchen.
If plugging the K-Slim into other outlets works, then you are in luck because the problem is not with your machine.
You can also try plugging other kitchen appliances, like a toaster or a blender, into the power outlet where you usually plug the K-Slim. If they work, then your Keurig might be the problem.
You can check if there are problems with the reservoir, power cord, or other parts of the Keurig. Alternatively, you can also call Keurig’s customer support for help. They may replace the whole unit or repair your brewer for free if it is still under warranty.
Damaged Power Cord
If other kitchen appliances still work while plugged into your kitchen outlets, your Keurig’s power cord may be damaged. Check for any physical damage in the K-Slim’s power cord and see if any electrical wires are visible.
If the power cord is damaged and the casing has melted off, you will need to have the power cord replaced. If you are a handy person and are experienced in electrical DIY projects, you can buy a power cord and replace it yourself.
However, do take note that replacing Keurig parts by yourself can void the warranty so you might want to check if your K-Slim is still under warranty.
Excessive Buildup
If you haven’t descaled your Keurig in a while, the descaling process might not be completed because of the excess mineral deposits that are clogging your machine.
The descaling process might have also caused the K-Slim to overheat, especially if the machine requires a couple of water-only cycles.
If you suspect that this is why your K-Slim won’t turn on again after descaling, unplug the brewer and wait for a few minutes before plugging it in again. If your brewer powers back on, you can run a water-only brew cycle again to get the water line flowing properly again.

Thermostat is Overheated
As I mentioned earlier, Keurigs can overheat during the descaling process if you run a couple of water-only brewing cycles. This can cause the internal thermostat to overheat as well.
When the Keurig overheats, it can trip the internal thermostat and turn your Keurig off. There is a fix for this but you will have to open your K-Slim up to reset the thermostat.
You can open up the K-Slim by removing the four screws on the bottom of the machine. Once you have removed the screws, you can take out the panel behind the water reservoir and take out the rest of the K-Slim panels.
Find the thermostat and reset it with a paper clip. The thermostat has a small circular disk with a small reset hole in the middle and it can be easy to find. You may need to turn the K-Slim sideways to be able to reset the thermostat.
Take note that you won’t be removing any wires or any internal part of the K-Slim. You only have to remove the K-Slim’s body to access the thermostat.
Once you’ve reset the thermostat, assemble the K-Slim and plug it in. It should turn on and work properly again. You have to take note that opening up and resetting the thermal switch can void the warranty.

If your K-Slim is still under warranty, you can call Keurig customer support and tell them about the issue you are facing. You may still be eligible for repair, part replacement, or a whole unit replacement.
When to Call Keurig Customer Support
I personally am not a handyman so for any broken appliances I have, I immediately call customer support or a repairman to fix things up for me.
However, if you think you can fix your K-Slim by tinkering with it, you can definitely do so! You might even be able to fix your machine for free.
But, if you are like me, you can call customer support the moment you see that your Keurig is not working already. If your Keurig is still under, the more you have to call Keurig customer support ASAP so they can assess the damage.
If they find that the machine is faulty, they can send you a new replacement. But, if your Keurig is still under warranty and you’ve tinkered with it before calling customer support, your warrant might not be honored.
So, make sure to have Keurig’s customer support contact details within reach so you can contact them easily. You can visit their website, call 1-866-901-2739, or write them an email regarding your concern.
Final Thoughts
There can be several reasons why your K-Slim suddenly stopped working after descaling it. Make sure to try troubleshooting it before throwing it away as it might still be fixed!
