Error E16 on a Bosch dishwasher

It can be annoying and perplexing when the E16 error code appears on your Bosch dishwasher. Although this error typically denotes a water supply issue, it doesn’t have to ruin your day.

It can save you time and money to know what the E16 error means and how to fix it. Many times, a few quick checks and tweaks can quickly fix the problem.

We’ll walk you through the process of troubleshooting and fixing the E16 error on your Bosch dishwasher in this article, allowing you to resume enjoying clean dishes without any hassle.

Diagnostics plan for a dishwasher

When you see the error E16 on the dishwasher display, don’t contact a technician right away. It is not always necessary to repair the "home assistant"; occasionally, there is not even a malfunction. From simple to more complex, the check is carried out, eliminating each potential issue as it arises.

First things first. Verify that the house’s water supply hasn’t been turned off. Open the kitchen or bathroom faucet to accomplish this. Analyze the pressure if water flows. Next, see if the pipe’s shut-off valve is closed. If it is, this could be the cause of the dishwasher’s emptying.

Examine the inlet hose next. It might be pinched or kinked. Verify that the leak protection system has not been activated (the hose block’s indicator will turn a different color in this scenario).

Another possible source of the issue could be a systemic infraction of tightness. Thus, ensure that the Bosch dishwasher door closes securely. It’s possible that the lock is broken and big dishes are in the way. It will suffice in this instance to partially empty the dishwasher.

You will need to search for a malfunction within the machine if none of the hypotheses turn out to be accurate. Error E16 may result from:

• a faulty inlet solenoid valve (in this case, the sensor membrane remains closed, and water cannot enter the dishwasher);
• broken door lock (the lock does not work, the system remains leaky, the module does not give the command to fill with water);
• a broken pressure switch (the level sensor transmits information about the filling of the washing chamber, and if it breaks, it can “lie”, reporting that there is enough water inside, while the machine is empty);
• a damaged control module (the electronic unit controls the operation of all dishwasher units, and its breakdown can provoke any error code).

You can solve most problems on your own. Let’s see if we can resolve this or that issue so that we can reset the E16 error that causes the dishwasher to operate more slowly.

A twisted water supply hose

An inlet hose that has kinked is a fairly common issue. When moving equipment, the corrugation is typically accidentally pinched. Water will not pass through the hose, for instance, if it gets under the dishwasher’s leg.

As an alternative, furniture or other appliances in the house could pinch the hose. Either way, you have to get rid of the obstruction as quickly as you can.

A leaking hose may even blow in this scenario, drenching the surrounding area in water. This is the reason it is crucial to keep an eye on the sleeve’s condition. First things first, the corrugation is examined when error E16 arises.

When a Bosch dishwasher displays error E16, it usually means there is a problem with the water intake, which means the machine isn’t getting the water it needs to function properly. Problems like a kinked hose, a clogged filter, or a broken water inlet valve can be the cause of this. Time can be saved and possibly avoided by knowing the typical causes and how to troubleshoot them.

The head of the tee tap is “turned off”

A tee tap is typically installed on the pipe prior to it entering the dishwasher or washing machine. When needed, it’s beneficial to turn off the dishwasher’s water supply without affecting the kitchen sink’s water supply. This valve occasionally fails.

Verify that the valve is open because the error E16 can occasionally be caused by something as simple as a closed tee tap.

Certain taps are delicate and easily broken when in use. Such a valve will eventually have a turning handle, but the flap will stay closed. As a result, water will not begin to flow into the device.

Given that the handle turns in this scenario, it will appear that the tap is not the issue. But craftspeople deal with this kind of issue all the time. As such, it makes no sense to rule out the chance of a shut-off valve malfunction.

The problem is hidden between the valve and the hose

A clogged mesh filter is another cause of the Bosch dishwasher’s inability to fill. The element is mounted in front of the inlet valve at the dishwasher’s entrance. Its job is to catch contaminants found in tap water and keep them out of the dishwasher.

Water will not enter the machine if the filter is not cleaned because over time the mesh holes will clog. Consequently, an error code will appear on the dishwasher. You must clean the element in order to resolve the malfunction. This is carried out in the manner described below:

• de-energize the dishwasher;
• use the shut-off valve to shut off the water supply to the machine;
• unscrew the inlet hose from the housing;
• find the mesh filter – it is located at the junction of the hose and the machine;
• remove the filter and rinse it in warm water.

Cleaning the mesh with a needle and putting it under the running tap will suffice if the contamination is not too bad. If the buildup on the filter has become solid, immerse the affected area in a citric acid solution for a few hours and then wash the component with warm water.

Is the door closing sensor triggered?

If the dishwasher door is not shut all the way, water will not begin to fill it. If the dishwasher’s "brain" doesn’t get a signal indicating that the system is sealed, it won’t fill. Thus, make sure to check:

• the integrity of the door sealing rubber (if there are any cracks, if the gasket is coming off the body);
• if the dishes are creating obstacles for the lock to operate;
• if the latch of the locking mechanism is damaged (after starting the cycle, there should be a click, which will tell you that the lock has been activated);
• if the machine is level (this can be checked using a building level).

Occasionally, the obstruction preventing the door from shutting is big plates. Rearranging the cutlery or slightly emptying the machine will solve the error in this instance. Tighten the dishwasher’s legs to level it if it is not.

You’ll need to replace the rubber if the damaged seal is the source of the issue. A broken lock may be attempted to be fixed, but installing a new blocker is simpler. The locking mechanism is inexpensive.

The following will be the sequence of events when the lock is replaced:

• open the dishwasher door;
• remove the screws located on the inside of the door and on the ends;
• remove the upper part of the door;
• take a photo of the wiring diagram to the lock;
• disconnect the wires from the locking mechanism;
• after dealing with the fasteners, remove the blocker;
• install a new lock, fix it, connect the previously reset wiring;
• return the door part to its place, secure the panel with screws.

Make sure the lock is operational by running a brief test cycle after that. The error will go away if the system leak was the cause of the issue.

The valve has stopped functioning

The component in charge of filling the Bosch dishwasher is the inlet valve. Water starts to enter the chamber when the sensor membrane is opened by the electronic module. Should the electromagnetic valve malfunction, the dishwasher will not function.

You must first check the element for damage. A multimeter is then used to check the inlet valve. The resistance that the part produces is measured by the tester. In the event that it is absent, the sensor cannot be fixed; a new one must be installed instead. The following will be the algorithm:

• disconnect the wiring from the electromagnetic valve;
• unscrew the bolts that secure the part;
• remove the sensor;
• install the new valve in its original place, secure it with screws;
• connect the wiring.

To ensure that replacing parts doesn’t impact the dishwasher’s functionality, only purchase original spare parts when repairing a Bosch dishwasher.

After the inlet hose is attached to the body, open the shut-off valve and connect the device to the network. Run a test wash after that. The dishwasher should be able to be restarted and the fault code reset by replacing the inlet valve.

When a Bosch dishwasher displays error E16, it usually means that there is a problem with the water flow or level. Although it may initially seem concerning, many of the fixes are simple and doable at home.

Start by looking for obstructions in the filters and water inlet valve. Frequently, the problem can be fixed by making sure these are clean and operating correctly. It might be essential to check the flow sensor or get expert assistance if the issue continues.

Resolving the E16 error as soon as possible will keep your dishwasher operating properly and stop future issues. Maintaining your appliance on a regular basis and responding promptly to error codes will help it last longer and prevent expensive repairs down the road.
