You’re probably wondering what’s wrong if your Candy dishwasher started showing an Error E4 code out of the blue. Although this error can be annoying, knowing what causes it can help you find a quick solution. Usually, the E4 error indicates that there is a problem with your dishwasher’s drainage system.
It helps to check a few things in order to determine the root of the problem. First, make sure there are no kinks or obstructions in the drain hose. This blockage has the potential to cause improper drainage and error. Examine the dishwasher’s internal filter as well, as a build-up of debris can result in comparable issues.
Should these inspections prove ineffective, there may be a problem with the drainage pump itself. Since this is a bit more complicated, if you’re not comfortable doing repairs yourself, you might need to hire an expert. When it comes to fixing your dishwasher, knowing what’s causing the E4 error can ultimately save you time and aggravation.
What to do when the E4 code appears?
Candy dishwashers provide various methods of information regarding the "Aquastop" system’s activation. On some, the error code is shown on the screen. On models without a digital display, some of the control panel’s LEDs illuminate. Additionally, the indicator on the PMM’s inlet hose takes on a reddish tint.
Examine the instructions that came with your Candy dishwasher to gain an understanding of how the device notifies you when Aquastop is activated.
Ways to reset the error code E4? Identifying the source of the leak is essential. Examine the dishwasher’s inlet hose first. If the indicator on it turns red, the corrugation will probably need to be replaced.
The sensors in the Aquastop system are unique. If the dishwasher in your home is mechanical, changing the hose is not required. It will be sufficient to undo the spring and force the device’s membrane inward.
Modern Candy dishwashers have inlet hoses that are not reusable once Aquastop is engaged. You will need to replace the corrugation in such a case. Thus, everything is dependent upon the kind of sensor used in the leak protection system.
It’s very easy to replace the dishwasher’s inlet hose. It is imperative that:
- de-energize the dishwasher;
- turn off the tap responsible for the water supply to the machine;
- unscrew the old hose first from the PMM, then from the point of connection to the water supply;
- connect a new hose.
In the event that the Candy dishwasher has electromagnetic protection, you will also need to connect the wire to a leak detection sensor. The dishwasher’s inlet valve is close to the groove where the cable is meant to be connected.
Water in the dishwasher tray is actually the root cause of the E4 error. The repair will be more difficult in this case. To find the leak’s source, you’ll need to disassemble the machine. It is preferable to give such tasks to an expert.
When your Candy dishwasher displays the error code E4, it usually indicates that there is a problem with the water drainage system of the device. This post will examine the typical causes of Error E4, such as problems with the drain pump, filters, and hoses, and offer helpful troubleshooting techniques to assist you in fixing the problem and getting your dishwasher operating at peak efficiency again.
How the liquid got into the tray?
What should be done if a leak is discovered by the Candy dishwasher? First, give it some time until the machine empties the working chamber’s water into the sewer. Following this, you must turn off the equipment’s power supply, shut off the shut-off valve, and begin investigating the malfunction’s cause. We will identify the possible issue for you.
- External leak. Sometimes the E4 error appears due to accidental water getting into the dishwasher tray. For example, when one of the family members spilled tea near the machine. Check if the pipes near the dishwasher are leaking. All this can lead to the activation of the Aquastop system.
- Clogged filters. In this case, the circulation of liquid inside the machine is disrupted. This leads to problems with drainage and overflow of the dishwasher. As a result, water gets into the tray. The float rises up, the leak protection system is triggered. The solution to the problem is to clean the filter unit and "dry" the dishwasher.
According to the manufacturer Candy, you should clean the dishwasher’s filter unit at least once a week and remove any large debris after each use.
- Using an unsuitable dishwashing detergent. Some housewives pour regular gel into the dispenser, for example, Fairy. It is characterized by increased foaming, and this is unacceptable for Candy dishwashers. Soap bubbles leak through the dishwasher door and also get into the tray, causing error E to appear. In this situation, you will have to immediately turn off the machine and leave it to dry for a few days. Using household chemicals for hand washing is fraught not only with the activation ofAquastop, but also with damage to the electronic module of the device.
- Violation of the dosage of detergent. Even using special household chemicals for the dishwasher, you can load too much powder into the machine, which will also lead to increased foaming. The foam will get into the tray, the equipment will give an error E The solution to the problem will be similar – the dishwasher should be left for 2-3 days so that it dries.
- Pouring waste liquid from the sewer. A fairly rare malfunction, but you should not exclude its possibility. This can only happen with dishwashers connected to a siphon. Waste water gets from the pipe into the machine, to which the latter reacts with an error E The solution will be to clean the "elbow" and install a check valve, which will prevent waste water from pouring into the dishwasher.
In order to stop sewer waste liquid from entering the dishwasher, the drain hose needs to be placed in accordance with all guidelines, which call for it to be looped at the sink’s level. It is also possible to connect the corrugated pipe straight to the pipe rather than through the siphon. Putting in a "knee" with a check valve is an additional choice.
Simply tilt the dishwasher backward to empty the water tray. For some models, the liquid cannot be removed until the side wall of the case has been removed. Another choice is to simply leave the dishwasher’s door open for two to three days without touching the machinery; the dishwasher will then dry itself.
