Understanding CDA Dishwasher Fault Codes and How to Address Them
Dishwashers have become common in kitchens today, making the otherwise tedious work of washing dishes a whole lot easier. But when that trusty old CDA dishwasher suddenly begins showing nonsensical fault codes, it quickly becomes frustrating puzzle work. What exactly do these codes mean? And more importantly, how to fix the issues they represent?
Below, some common CDA dishwasher fault codes will be explained, including what they mean and the steps one can take to troubleshoot and resolve them. By the end, you will be in a better position to handle those blinking lights and error beeps with confidence.
What is a CDA Dishwasher Fault Code?
Fault codes are the dishwasher’s way of telling you that something is wrong. Think of them as a language between the machine and its user. When something isn’t functioning correctly, the dishwasher displays a code to help you-and any technician-identify the issue.
Fault codes save you time by narrowing down possible problems. Once you know what a given code means, you can decide whether it’s something you can fix yourself or if it’s time to call a professional.
Important Note: Before attempting any fixes, remember to turn off and unplug your dishwasher to ensure your safety.

1. E1 – Water Supply Issue
What it means: The dishwasher cannot fill with water due to a supply problem.
How to fix it:
- Check that the tap of the water supply is turned on and running well.
- Check the hose for kinks or blockages.
- Check the water pressure is within the required range as stated in your machine’s manual.
2. E2 – Water Drainage Problem
Meaning: The water is not draining as it should from the dishwasher.
Solution:
- Look out for kinks, twists, and blockages on the drain hose.
- Pull out the filter of the dishwasher and give it a good clean, as this is generally packed with food debris.
- Check for blockages in the sink connection where the drainage hose hooks up.
3. E3 – Heating Issue
What it means: The heating system is not able to heat the water inside the dishwasher properly.
How to fix it:
- Check if the problem is with the heating element. This usually involves calling a professional to replace it.
- Check the thermostat to see if it’s working. It could be that a duff thermostat can’t detect the rise in temperature.
4. E4 – Water Overflow Error
What it means: There is too much water in the dishwasher; this could mean a problem with draining or a leak in it.
How to fix it:
- Ensure the drain hose is not clogged, which may be causing the water to back up into the dishwasher.
- Check the bottom of the dishwasher for any signs of leakage. Use a towel for absorbing the water and see if the problem reoccurs in the next cycle.
- Check that the float switch, which operates the water levels, is not stuck.
5. E5 – Motor Fault
What it means: The circulating/drain motor is malfunctioning.
How to fix:
- Check wiring at the motor terminals for cuts and disconnections.
- Run the dishwasher and listen. If it’s making unusual noise-straining, rattling-the motor likely needs a professional repair or even replacement.
6. E6 – Fault in Water Sensor
What it indicates: The water level sensor can’t detect the levels of water as required.
How to go about it:
- Check for dirt or mineral buildup on the water sensor; cleaning might get the job done.
- When cleaning doesn’t work, replace the sensor.
7. E7 – Not Properly Closed Dishwasher Door
What it means: The dishwasher believes the door is open, while to the naked eye, it looks closed.
How to fix it:
- Check the door latch, ensuring nothing is obstructing its closure. It could be that the latch mechanism is loose or damaged.
- Ensure the hinges are tight and aligned properly.
8. E8 – Spray Arm Blocked
What it means: Spray arm obstructed or not rotating freely.
How to fix it:
- Check the spray arm for any food particles and other debris that could be obstructing its holes.
- Ensure the spray arm is free to rotate and isn’t obstructed by dishes during a cycle.
Quick Tips for Preventing CDA Dishwasher Fault Codes
Preventive measures to minimize these irritating codes from occurring in the first place include the following:
- Clean filters regularly: Avoid blockages by cleaning your dishwasher’s filter at least once a month.
- Correctly load dishes: Do not overcrowd the dishwasher, as this may block spray arms and promote improper washing of dishes.
- Check on the hose periodically: These are in the form of signs of wear, kinks, and blockage on both supply and drainage hoses.
- Use proper detergent: Check the dishwasher manual to ensure you are using a recommended brand, as many products may build up unnecessary residue. However, there are ways to keep it up without having to call professionals too often: run an empty cycle with dishwasher cleaner or vinegar to clean grease and mineral deposits.
While the above basic steps will help fix most of the fault codes in your CDA dishwasher, some cases need expert assistance. If trying the above makes the issue persist or results in more critical issues that could be potentially noticed by other means, including weird noises and smell, the service of an expert technician becomes crucial. Taking the right corrective measure at an opportune moment ensures long life, efficiency, and a prolonged duty cycle of your appliance.
Conclusion
Understanding CDA dishwasher fault codes can be a chore. These kinds of codes tend to point the way to easy resolutions of problems and issues that relate to clogs in the drains, heating failures, and more complex door catches. A small amount of troubleshooting will often resolve many issues on their own.
By being proactive with the maintenance and rectifying the fault codes as soon as they pop up, you can keep your dishwasher running right—and your kitchen routine hassle-free.
