Faucet error in Bosch dishwasher: 7 causes and solutions

Dishwasher Bosch suddenly stopped and a message appeared on the display "faucet" or is the water tap indicator blinking? This error is one of the most common in the series models SMV, SMS, SPV and others. It signals problems with water supply, but there can be a dozen reasons: from a banal bend in the hose to failure of the valve or electronics.

In this article we will analyze all possible reasons "faucet" errors - from simple to complex - and we will also give step by step instructions for diagnostics and repair. You'll learn how to check water pressure, test the fill valve, clean filters, and reset errors. And if the problem turns out to be more serious, we’ll explain when the call of the master is inevitable and how much it will cost.

⚠️ Important: Don't ignore this error! Operating the dishwasher for a long time without water can lead to overheating of the heating element (heating element) and its breakdown. Some models Bosch (for example, SMV68TX06R) the protection is triggered, but it’s not worth the risk.

Before disassembling the machine, check three basic points:

1. Is it open water supply valve under the sink?
2. Are there any kinks or creases on inlet hose?
3. Is it enough pressure in the water supply (minimum 1 bar)?

If everything is in order, but the error does not disappear, read on. We have compiled diagnostic checklist and detailed instructions for each case.

1. What does the “faucet” error mean in a Bosch dishwasher?

Message "faucet" (or water tap icon) on the display Bosch points to lack or insufficient water pressure in the system. In the manufacturer's technical documentation this error is indicated as:

• E1 — in older models (before 2015);
• E:01 or E01 - in new series (for example, Bosch Serie 6);
• Faucet indicator - if the display does not have a digital display (models SPV40X30, SPS40E32).

The error occurs when:

1. The machine cannot draw water within 10–15 minutes after the start of the program;
2. The flow sensor does not detect water flow through the fill valve;
3. The electronics receive a low pressure signal (less than 0.5 bar).

Critical Feature: In models Bosch with the system EcoSilence (for example, SMV68TX06R) the “faucet” error can appear even with minimal water interruptions - due to the increased sensitivity of the sensors. This is done to protect the heating element from “dry” heating.

2. Top 7 causes of the “faucet” error and how to check them

Let's look at all the possible reasons - from the simplest to the most complex. Start your diagnosis at the first point and work your way down until you find the source of the problem.

2.1. The valve is closed or there is no water in the system

The most common reason is closed tap under the sink or turning off the water in the house. Check:

• 🔧 Open the water supply valve (usually located under the sink or next to the dishwasher);
• 💧 Make sure that water flows from the faucet with normal pressure;
• 📞 If there is no water in the whole house, call the management company.

⚠️ Attention: Some houses have check valves on risers that can block the water supply at low pressure. If the pressure is weak, try turning on the dishwasher at night - when water consumption in the house is minimal.

2.2. The inlet hose is kinked or clogged

The hose may have become kinked during installation or become clogged with rust/sand. What to do:

1. Unplug the machine and turn off the water;
2. Disconnect the hose from the dishwasher and check it for kinks;
3. Blow out the hose or rinse under a strong stream of water;
4. Check mesh filter at the end of the hose (often clogged with rust).

2.3. Dishwasher inlet filter is clogged

Inside the machine, where the hose is connected to the body, there is metal mesh. It traps debris, but becomes clogged over time. How to clean:

1. Unscrew the hose nut (you will need a 19 or 22 wrench);
2. Remove the filter mesh with tweezers or pliers;
3. Rinse it under water and clean it with a toothpick;
4. Reinstall and tighten the nut securely.

What happens if you don't clean the filter?

Ignoring a clogged filter leads to reducing water pressure and increased load on the filling valve. As a result, the valve may burn out, and replacing it will cost 2–4 thousand rubles.

2.4. Fill valve faulty

The valve is responsible for opening/closing the water supply. If it breaks, the machine will not be able to draw water. Signs of malfunction:

• 🔊 The valve does not click when the dishwasher is turned on;
• 💦 Water does not flow, although there is pressure in the system;
• 🔥 Traces of melting or rust are visible on the valve body.

How to check:

1. Remove the top cover of the dishwasher (unscrew 2-4 screws from the back);
2. Find the valve (usually on the bottom right, there is a hose going to it);
3. Check the valve coil resistance with a multimeter (should be 2–4 kOhm);
4. If there is no resistance, the valve is burnt out and requires replacement.

2.5. Broken flow sensor (flow sensor)

Flow sensor (or pressure switch) monitors the amount of incoming water. If it fails, the machine “thinks” there is no water and generates an error. Symptoms:

• 🌊 Water is gathering, but very slowly;
• 🔄 The program is reset 1-2 minutes after start;
• 📊 The “faucet” indicator flashes on the display, although there is water.

How to check:

1. The sensor is located next to the fill valve (plastic case with wires);
2. Remove the hose and blow out the sensor - you should hear a click;
3. Check the resistance with a multimeter (normal: 0.5–1 kOhm).

2.6. The control unit is clogged or broken

If all mechanical elements are working properly, the problem may be electronics. Most often they fail:

• 🧠 Filling valve control microcircuit;
• 🔌 Valve activation relay;
• 📶 Contacts on the board (oxidation or breakage).

Repairing the board yourself is difficult, but you can:

1. Disconnect the machine from the network for 10 minutes (reset errors);
2. Inspect the board for availability dark spots, swollen capacitors;
3. Wipe the contacts with alcohol (if there is oxidation).

⚠️ Attention: If the board shows signs of burning or burnt tracks, do not try to repair it! This may lead to short circuit or fire.

2.7. Low water pressure in the system

Dishwashers Bosch require minimal pressure 1 bar. If the pressure is weaker, the machine will not be able to draw water. How to check:

• 🚰 Open the tap fully - if the stream is weak, the problem is in the water supply;
• 📏 Buy a pressure gauge and connect it to the dishwasher hose;
• 🏢 Check with the management company to see if any repair work is underway.

3. How to reset the “faucet” error after eliminating the cause

After repair, the error must be reset. The methods depend on the model:

Model Bosch	Reset method	Notes
Serie 2/4 (SMV25EX01R, SMS24AW01)	Unplug for 5 minutes	Suitable for 90% models without display
Serie 6 (SMV68TX06R, SPV68X30)	Press and hold Start 10 seconds	Works if the error is not critical
Serie 8 (SMV88TX06E, SPV88X30)	Clamp Start + Program 1 for 3 sec.	You may need to reset again
Models with Home Connect	Reset via app (Settings → Reset errors)	Wi-Fi connection required

If after resetting the error appears again, the problem is not resolved. Return to diagnostics (section 2).

4. When to call a specialist: repair prices

Not all breakdowns can be fixed on your own. Contact a specialist if:

• 🔧 Burned out fill valve (replacement - 1,500–3,000 ₽);
• 🧠 Out of order control board (repair - 3,000–6,000 ₽);
• 💦 Damaged flow sensor (replacement - 2,000–4,000 ₽);
• 🔥 Burned out heating element due to work without water (replacement - 2,500–5,000 ₽).

Average prices for repairs in service centers (2026):

Type of repair	Cost (₽)	Deadlines
Diagnostics	500–1 000	30–60 min
Replacing the fill valve	1 500–3 000	1–2 days
Control board repair	3 000–6 000	3–5 days
Replacing the flow sensor	2 000–4 000	1–2 days

⚠️ Attention: If the dishwasher is under warranty (up to 2 years), don't take it apart yourself - this will void the warranty. Contact an authorized service Bosch.

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

To prevent the problem from recurring, follow these tips:

• 🔄 Once every 3 months clean the mesh filter on the inlet hose;
• 🚰 Install coarse filter on a water pipe;
• 🛠️ Check once a year hose tightness and connections;
• ⚡ Use voltage stabilizer — power surges damage electronics;
• 📱 Update the firmware via Home Connect (for smart models).

6. Frequently asked questions about the “faucet” error in Bosch dishwashers

❓ Why does the “faucet” error appear only on some programs?

In modes Intensive wash or Auto the machine consumes more water, and if the pressure is weak, the error appears only on them. Check water pressure and cleanliness of filters.

❓ Is it possible to use a dishwasher if the error appears rarely?

No! Even if the error occurs sporadically, this indicates problem with water supply. Long-term operation in this mode will lead to breakdown of the heating element or electronics.

❓ What to do if the “faucet” error appears after moving?

Most likely, the hose came loose or got bent during transportation. Check:

1. Connecting the hose to the water supply;
2. The integrity of the hose (are there any cracks);
3. Position of the machine (should be level, not tilted).

❓ Why does the error not reset after the cause is eliminated?

In some models (for example, Bosch Serie 8) the error is recorded in memory. Try:

1. Disconnect the machine from the network for 10–15 minutes;
2. Click Start + Program 3 for 5 seconds;
3. Reset settings to factory defaults (Settings → Reset).

❓ How much does self-repair cost?

If you replace the parts yourself, the costs will be minimal:

• Filling valve - 800–1,500 ₽;
• Mesh filter - 100–300 ₽;
• Flow sensor — RUB 1,200–2,000;
• Hose with aquastop - 500–1,000 ₽.

For repairs you will need: a screwdriver, pliers, a multimeter (for checking electronics).
