How to Decode CDA Dishwasher Fault Code F5
A dishwasher is one of those very convenient appliances in the modern kitchen. When they go wrong, though, it can very quickly make life a bit difficult. So, if you’re seeing this F5 fault code on your CDA dishwasher, you may be wondering what that means and how you can fix it. This post will break down the issue and explain the probable causes; it then walks you through possible solutions-no technical jargon, just plain, simple advice.
What does F5 Fault Code Mean?
The most common faults occurring in CDA dishwasher have an F5 fault code related to problems in the draining system. It would, therefore, imply inability to drain water out properly in the dishwasher. The reasons can be many and knowing those reasons is pretty much the basic solution to the problem.
The most common causes that can trigger this code include a clogged drain filter, a clogged drainage hose, a faulty wastewater pump, and an internal drainage system problem of the dishwasher. Since we have seen what this fault code means, let’s go ahead with troubleshooting and fixing this.

F5 Fault Code Fixing Steps
Before trying to fix anything, remember to always switch off the dishwasher and unplug it from the power source for your safety. The following steps will help you identify and resolve the issue.
1. Check the Drain Filter
The drain filter catches food particles, debris, and other residues during a wash cycle. Over time, this can become clogged, leading to drainage problems.
- Find the filter: mostly located at the dishwasher’s bottom, around the spray arm.
- Clean and inspect: remove the filter and check if it has a blockage in it. Rinse well under running water. Use a soft brush if required to remove stubborn deposits.
- Reattach the filter; check on how the dishwasher is working. If the code persists, go to the next step.
2. Check Drain Hose
The drain hose carries the waste water from the dishwasher into the sink or drainage. If this is clogged or kinked, then water would not drain properly.
- Locate the hose: Usually, it is connected to the back portion of the dishwasher.
- Clear the blockage: Gently disconnect the hose and check for blockages. Run water through it to ensure a blockage in the hose. If so, just flush it out.
- Check kinks: The hose shouldn’t be kinked, twisted, or ill-positioned.
- Reconnect the hose and check the system.

3. Wastewater Pump
The wastewater pump serves the purpose of pushing water from the dishwasher. If it is defective or clogged, it could also be a reason for the F5 code.
- Locate the pump; it is usually at the bottom of the unit.
- Check around the pump impeller for blockages. Clean it carefully.
- Replace if damaged. This would require a technician to change for you unless you’re experienced with repairing appliances.
4. Check the Internal Drainage
If the filter, hose, and pump appear fine, the problem could lie in the dishwasher’s internal draining mechanism.
- Make sure all internal pipes/drainage channels are free of blockages; this may occasionally need professional service.
5. Start Up the Dishwasher
Once you’ve completed the above steps, reset the dishwasher to clear the fault code. Refer to your dishwasher’s user manual for reset instructions. Typically, unplugging the machine for a few minutes and then reconnecting it can do the trick.
If the F5 code would still appear after these steps, you might have a more serious problem, in which case you should contact CDA’s customer support or a professional appliance repair service.
