E2/E3 Error Code Troubleshooting Guide
This guide can also be used with models EL7061A, EL7062A, EL7063A, EL7066A and the EL7070A
The El7060 series canister vacuums have a LCD display which usually displays the power level of the suction motor but will also display error codes when the system detects a problem. This guide will walk through the most common issues that cause these codes.
Note, the pictures used in this guide are from various models in the EL7060 series, so some of the testing procedures depicted may vary slightly depending on the model you are working on.
Checking the Hose and Wand:
To begin troubleshooting you will want to test the hose and wand to ensure they are functioning properly. In many cases where damage has been caused to the electronics such as a blown fuse, the hose and/or wand is the root problem and should be replaced.
If there is no obvious damage to the electronics try testing a known good hose/wand if you have them available to you. If you do not have access to these items follow the procedures below troubleshoot:
Wand: First check the pins for breakage where they are "held" by the wand.
If there is no breakages check the wires connected to the pins by snapping off the cover and inspecting the connections.
Hose: Next check the connections to the hose buttons. You will need to remove the frame, remove the buttons and springs, and then remove the screw holding the switch PCB.
If the wire connections are loose pinch them to ensure they grip the contacts properly.
Checking the Canister (E2 Error):
The E2 Error is caused when there is a communication problem between the hose and the canister. After checking the hose and wand you will want to move on to checking the connector piece which the hose plugs into. Follow the Troubleshooting or Assembly/Disassembly guide under the Service Manuals section for the model you are working on if you are having problems reaching the connector.
Once you have access to the connector inspect the wire connections and make sure it is positioned with in the housing to ensure the pins line up.
It is also a good idea to check the connectors to make sure they aren't bent back, preventing the hose pins from making good contact.
If the connector looks good then move on to the power supply board. This board has a hard-wired fuse which you will need to replace if blown. It will be located on the side of the canister and is labeled as part #1181870-0X, where X is a number (this is the revision number and is subject to change). When replacing the circuit boards we generally recommend replacing both of the power boards in the machine. This would mean you would want to replace the PCB Power Module as well.
Note: In some of our tests we have noticed that the machine will display an E2 error code when switched on while there is no hose connected. If a unit is displaying an E2 code and you are testing it. be sure to make sure to make sure the hose is connected. Otherwise the machine detects the disruption in communication. See pictures below for an example.
E2 Error Code Example:
For testing purposes we left the dust bag cover and hose off the unit. Even if the cover is on the error will display if no hose is connected. The unit will run for less than 1 second or not turn on at all, and then flash 'E' and '2' sequentially. If the machine is displaying this error code while the hose is connected follow the steps above to fix the issue.
Checking the Canister (E3 Error):
If the machine is displaying an E3 error there may be a communication problem between the circuit boards in the canister. Begin by checking continuity on the black and white cables running from the Power Supply PCB to the Power Module PCB. Also check to make sure all connections between the two boards are solid as well as the connections to the Display Board.
E3 Error Code Example: In this example the black Cable Running between the Power Supply and the Power Module Boards was disconnected to simulate damage to the cable or the Power Module or a loose connection between any of the boards. The machine will start to run, cycling through the power levels to 5, after which it will cut out and display 'E' and '3' sequentially.
Final Comments:
If the machine is still not working after checking everything mentioned above there is a chance that the boards are damaged, even if there is no visible damage. Replace both the Power Supply PCB and the Power Module PCB. As mentioned before, make sure you test the hose and wand as they can continue to damage circuit boards if there is a problem and it is not connected.
Also, if the power head stops working try disconnecting it from the machine and "jumping" it to see if it will turn on. If it doesn't there is most likely something wrong with the main board in the power head and/or the brushroll motor. If it does turn on then the canister is most likely experiencing problems similar to an E2 error. In this case it would be best to check the hose and wand for problems, as well as any possible connection problems in the canister and on the power boards. Replace anything that appears defective, and replace both boards if no other problems are evident.
