4 Quick Fixes

There might be diversified reasons behind the charging issue of the Eureka vacuum. Some issues are so common and minor that you can fix them within seconds. Contrarily, you can encounter some major issues occasionally that can need technician help, and you can’t overcome these issues yourself. Let’s discover the root causes and their potential fixes for various charging errors.

Reason 1: Malfunctioning Wall Outlet

Primarily, the common reason behind the Eureka cordless vacuum not charging can be the malfunctioning power outlet. Although it’s a reason that seems not very important and you can forget to check it at first.

Fix # 1: Check the Functionality of Plugs/Breakers

The first and foremost thing that plays a crucial role in the well-functioning of your corded or cordless appliances is the power wall outlet. Therefore, check its functionality by following these steps:

  • Plug the charger into the wall outlet. If your charger can’t fetch the output current, plug it out.
  • Then, try other devices or chargers to check the output power of the wall outlet.
  • If the other devices are working well, then the issue is in your charger.
  • If the other devices also fail to suck the power, then definitely the power outlet is faulted.
  • You can also try other power outlets in your home to check the credibility of the charger. It might be possible the charger pins are not fitted well to hold the power properly.

Pro Tip: Sometimes the breaker trips due to some issues, so don’t forget to check the breaker panel as well and reset the circuit breaker for better current flowing in the power outlet.

Reason 2: Faulty Charger/Battery

After checking out the functionality of power outlets, you should analyze whether the charger or the battery is at fault.

Fix # 2: Check Battery and Charger

Charger Testing:
  • To test the viability of the charger, you should first check its physical condition, whether it has a torn or frayed cord, damaged pin, or weary charging adapter.
  • If the charging cable is damaged, you can try another compatible charging cable if available.
  • If the charging cable is in good condition, the charger’s adapter creates issues. You can test it with an alternative compatible adapter.
  • Maybe the charger’s pin is loose and doesn’t fix the charging port properly.
  • You can also use the multimeter to check the charger output power.
  • The outer part of the charger pin is negative, and the inner part is positive terminal. So, attach the positive to the positive and the negative to the negative.
  • Now, switch on the charger and multimeter.
  • Set the voltages of the multimeter to 200V DC.
  • Then, assess the reading on the multimeter. The recommended voltages to charge your Eureka vacuum properly are from 26V to 29V.

If the charger is functioning well, then test the battery.

Battery Testing and Fixing:
  • Firstly, analyze the battery’s external condition.
  • Occasionally, the battery may be damaged, leaked, corrosive, or weary wires connection.
  • If the wire connections of the battery are weary, you can repair them easily.
  • On the other hand, if the battery leaks or is damaged, you must replace it to avoid any severe damage.
  • If possible, you can use an alternative compatible battery to check whether the battery is faulty or the Eureka vacuum is the real culprit.

Pro Tip: Check your battery age before testing it thoroughly. The old age battery and usage battery lose its charging capability with time.

Reason 3: The Corrosive or Dirty Charging Ports

Although the vacuum helps you to clean your surroundings very efficiently, the vacuum also needs to be cleaned properly after cleaning operations. Usually, the dust and debris accumulate in charging ports with time if you don’t clean it after usage.

Fix # 3: Clean the Ports Carefully

  • Take a cotton bud or toothpick to clean it.
  • Dampen the cotton bud in rubbing alcohol and rub the ports gently.
  • Don’t do the cleaning forcefully to prevent any damage.

Pro Tip: Don’t use metal tools to clean the charging ports; they might damage the circuit board.

Reason 4: Faulty Vaccum

While charging, If you feel some noise, smoke, or smell of any burning object, remove the charger from the vacuum to save it from any risk and contact a professional technician or Eureka service center.

Step 2: Software Glitches

Software and firmware issues can be a reason behind the charging errors of Eureka Vaccum. To
