Bosch dishwasher: what to do if the “faucet” error is on?

You loaded the dishes, started the washing program, but instead of the usual hum of the machine, an alarm indicator with the image faucet? This error is one of the most common in dishwashers. Bosch (especially in the series SMV, SMS, SPV). It signals problems with the water supply, but the reasons can be either trivial (forgot to open the tap) or serious (failure of a valve or electronics).

In this article we will look at all possible reasons faucet errors (including codes E1, E3, E15 and others), we will learn how to diagnose a malfunction without calling a technician and consider repair methods - from basic to complex. You will also learn how to reset the error and prevent it from recurring. If your car Bosch refuses to draw water or constantly “freezes” with the indicator on - read on.

What does the “faucet” error mean on a Bosch dishwasher?

Indicator with a picture of a faucet (or error code E1/E15 on the display) indicates problem with the water supply system. The machine either does not receive water at all or receives it too slowly. Depending on model Bosch, the error can manifest itself in different ways:

• 🔴 The red faucet indicator is on — critical malfunction, the sink is blocked.
• 🟡 Yellow indicator flashes — temporary problem (for example, low water pressure).
• 📛 Code E1, E3, E15 The display shows a specific error that requires diagnostics.

It is important to understand that the “faucet” error is not a death sentence. In 60% of cases the problem is solved without replacing parts (for example, cleaning the filter or checking the hose). But if you ignore the signal, it can lead to overheating of the heating element (heating element) due to “dry” operation or failure of the electronic module.

The main causes of the error and how to eliminate them

Let's sort it out all possible reasons, starting with the simplest ones. Before diagnosis unplug the machine and turn off the water supply.

1. Forgot to open the tap or the water was turned off

This is the most banal, but also the most common reason. Check:

• 🚰 Water tap under the sink - it should be open.
• 🔧 Ball valve on the outlet to the dishwasher - sometimes it is accidentally closed.
• 🏠 Central water supply in the house (if the error appeared after pipe repair).

If the tap is open but no water comes out, check system pressure. To do this, open any faucet in the house. If the pressure is weak, the problem may be in the home water supply (for example, an accident on the main line).

2. Inlet filter or water supply hose is clogged

Over time in coarse filter (located at the entrance to the machine, in front of the valve) rust, sand and other contaminants accumulate. It may also clog water supply hose.

How to clean:

1. Unscrew the hose from the machine and rinse it under water pressure.
2. Remove the filter (mesh) from the inlet and clean it with a toothpick.
3. Check check valve (if any) - it should not jam.

3. Inlet valve (solenoid) is faulty

The valve is responsible for opening/closing the water supply at the command of the electronic module. If he jammed or the coil is burnt out, the machine will not be able to draw water.

Signs of valve failure:

• 🔊 Clicks when trying to draw water (but no water comes out).
• 💧 Leakage from under the valve.
• 🔥 Burning or melting on contacts.

To check the valve you will need multimeter. Measure the coil resistance - it should be within 2–4 kOhm. If there is no resistance or it tends to infinity, the valve must be replaced.

How to check a valve without a multimeter

If you don’t have a tester at hand, you can apply voltage to the valve 220V (via extension cord with plug). A working valve should open with a characteristic click. Be careful! Working with tension requires experience.

Problems with the electronic module and sensors

If all mechanical causes are excluded, but the “faucet” error continues to light up, the problem may lie in electronics. Let's look at typical faults:

1. Control board failure

Electronic module (PCB) controls the operation of the valve, sensors and pumps. If there are power surges or moisture, it may generate false errors.

Signs of board failure:

• 🔄 The error appears by chance, for no apparent reason.
• 🖥️ The machine is “buggy” - it turns on/off by itself, does not respond to buttons.
• ⚡ Before the mistake there were power surges online.

First try reset error:

1. Unplug the machine for 10–15 minutes.
2. Turn it back on and run the test program (if available).

If resetting doesn't help, you may need to flashing or board replacement. This is a complex procedure that is best left to a service center.

2. The water level sensor (pressure switch) is faulty

The pressure switch controls the amount of water in the tank. If it fails, the machine “thinks” that there is no water and displays the “faucet” error.

How to check the pressure switch:

• 🔍 Take a look sensor tube - it must not be clogged or damaged.
• 📊 Check the resistance of the sensor with a multimeter (normal: 0–50 Ohm depending on position).

If the sensor is faulty, it must be replaced. The cost of a new pressure switch for Bosch - from 1,500 to 3,000 rubles.

Error codes associated with faucet problem

In dishwashers Bosch The “faucet” error can be accompanied by various codes. Let's break down the most common ones:

Error code	Description	Possible reasons	Solution
E1	No water supply	The tap is closed, the filter is clogged, the valve is faulty	Check the tap, clean the filter, test the valve
E3	Filling with water for too long	Low pressure, hose clogged, level sensor faulty	Check the pressure, clean the system, replace the pressure switch
E15	Water leak or overflow	Valve faulty, hose leaking, sensor faulty	Inspect the machine for leaks, replace damaged parts
E24	Water heating error (may be due to low level)	There is not enough water in the tank, the heating element or thermostat is faulty	Check water supply, test heater

If the display shows a code not listed in the table, contact operating instructions your model. For example, in machines of the series Bosch SMV68TX06R there may be an error E25, associated with the water turbidity sensor.

How to reset the “faucet” error on Bosch?

After eliminating the cause of the error, it must be reset. Here 3 wayswhich work on most models Bosch:

1. Soft reset:
   1. Press and hold the button Start/Reset within 5–10 seconds.
   2. If there is a display, select Reset in the menu (usually press and hold Program + Start).
2. Hard reset:
   1. Unplug the machine for 15 minutes.
   2. Turn it back on and run a short program (for example, Quick wash).
3. Reset via service menu (for advanced users):

   1. Turn on the machine.
   2. Press the buttons Program 1 + Program 3 for 3 seconds.
   3. From the menu, select Reset Errors (code 00).
   4. Confirm the reset.

If the error does not clear, this may indicate serious malfunction (for example, board damage). In this case, it is better to contact the service.

Prevention: how to avoid the “faucet” mistake in the future?

To prevent the faucet error from appearing again, follow these recommendations:

• 💧 Check the water pressure before starting the machine (optimally - 1–10 bar).
• 🧼 Clean the filter at the entrance every 3–6 months.
• 🔌 Use a voltage stabilizer, if your network has frequent surges.
• 🛠️ Check the hoses for wear and replace them every 5 years.
• ❄️ Don't let the water freeze in hoses (relevant for dachas).

It is also worth paying attention to water quality. If it is too hard, this leads to the formation of scale not only on the heating element, but also in the valve. Use water softeners or special tablets for dishwashers.

When to call a specialist? 5 signs of serious damage

Not all problems can be fixed on your own. Contact the service center if:

⚠️ Attention! If after checking the tap, filter and valve the error does not disappear and the machine doesn't pick up water at all, the problem may be electronic module. Repairing the board yourself without experience is fraught with danger complete breakdown of equipment.

• 🔥 Smells like burning or traces of melting are visible on the parts.
• 💦 The car is leakingand you can't find the source.
• ⚡ The error appears after a power surge.
• 🖥️ The display shows chaotic symbols or does not respond to buttons.
• 🔧 You have already replaced the valve and pressure switch, but the problem remains.

Cost of diagnostics at the service center Bosch starts from 1,000 rubles. Repairs will cost 2,500–10,000 rubles depending on the breakdown. Replacing the control board is the most expensive procedure (up to 15,000 rubles).

FAQ: Frequently asked questions about the faucet error

Is it possible to use the machine if the “faucet” error is on?

No. If the machine does not draw water, starting a program may cause heating element overheating (since it will run dry). This can lead to damage to the heating element and even a fire. Disconnect the machine from the network and eliminate the cause of the error.

The “faucet” error appeared after turning off the water. What to do?

Most likely there is air left in the system. Try this:

1. Unscrew the water supply hose from the machine.
2. Point it into the sink and turn the water on 10–15 secondsto bleed air.
3. Reconnect the hose and start the machine.

If the error remains, check valve and level sensor.

Bosch machine shows error E15. What does this mean?

Code E15 points to water leak or overflow. Check:

• Integrity of hoses and seals.
• Valve operation (it may leak).
• Level sensor (pressure switch).

If there are no visual leaks, but the error is on, it may have worked protective tray (available on some models). It needs to be dried.

How much does it cost to replace an intake valve at Bosch?

The cost depends on the model and region:

• Valve - from 1,200 to 3,500 rubles.
• Master's work - from 1,500 to 3,000 rubles.

For premium cars (for example, Bosch SMV88TX06E) parts may cost more. We recommend buying original spare parts, since Chinese analogues often fail due to 3–6 months.

Can I repair the valve myself?

Theoretically, yes, if the problem is clog or oxidation of contacts. But if the valve burned down or mechanically damaged, repair is impossible. In most cases, it is easier and more reliable to replace it with a new one.

To replace you will need:

• New valve (suitable for your model).
• Screwdriver and pliers.
• Multimeter (for checking).
