Before booking a visit — it's worth trying. We've gathered here the diagnostic checks we do ourselves in the field, step by step. Many faults are solved within a few minutes, without a technician and without waiting. If it isn't solved, you'll know exactly what to tell us — and that saves an extra visit.
Under-sink water system
No water from the faucet
- Check that the regular kitchen faucet works Open the regular kitchen faucet. If no water comes out of it either — there's no water in the home or the building, and it's not related to your system. Does water come out of the regular faucet?
- Check that the supply valve under the sink is open Under the sink there is a small valve that feeds the system. Handle parallel to the pipe = open, handle perpendicular = closed. It's sometimes closed by mistake after cleaning the cabinet or work by a tradesperson. Is the water back?
- If your system is electric — check that it has power Some systems are plugged into a socket under the sink, and some work without electricity at all. If your system has a plug — make sure it's in place, that the socket works, and that the breaker in the panel hasn't tripped. Is the water back?
- Wait a minute and try again Some systems have a protection that stops operation after long continuous use, and it releases by itself. If you've drawn a lot of water in a row — wait about a minute and try again. Is the water back?
Weak flow
- Compare with the regular kitchen faucet Open the regular kitchen faucet. If the pressure is weak there too — the problem is the water pressure in the home, not the system. It's worth checking with the building committee or the municipality. Is the pressure weak in the regular faucet too?
- Make sure the supply valve is fully open A small valve under the sink that is only partly open chokes the flow. Turn it to fully open and check again. Has the flow improved?
- Check when the filters were replaced A gradual drop in flow is the most common sign of a filter that has reached the end of its life — the first filter in the chain clogs first. The devices screen in the app shows the last replacement date. Has it been more than a year since the last replacement?
- If your system has a status indicator — look at it Some models have lights on the system body or an illuminated ring at the base of the faucet, which show when a filter is reaching its end. If you have such an indicator — check whether it has changed from its normal state. Does the indicator show that a replacement is needed?
Unusual taste or smell
- Flush the system Open the filtered-water faucet and let it run for about two minutes continuously. Water that has stood in the pipes overnight or after a holiday picks up a residual taste that disappears after flushing. Is the taste back to normal?
- Check whether the taste is also in the regular faucet Fill a glass from the regular kitchen faucet. If there's an unusual taste or smell there too — the source of the problem is the water supply, not the system. Is the taste also in the regular faucet?
- Check when the filters were replaced A filter past its time stops doing its job, and this is felt first of all in the taste and smell. Check on the devices screen when the last replacement was. Has it been more than a year since the last replacement?
- If the water is cloudy or coloured Fill a clear glass and stand it on a white surface for a few minutes. Milky water that clears from the bottom up is air bubbles, and that's normal. Cloudiness that remains, or colour — that's something else, and we'll want to see it. Did the water clear by itself?
Leak
- Immediately close the supply valve under the sink Turn the small valve that feeds the system to closed — the handle perpendicular to the pipe. This stops the flow and prevents damage. Don't take any connection apart yourself. If water keeps flowing even after closing the valve — close the main water valve of the apartment and call us immediately: 052-5958465 Did the leak stop after closing the valve?
- Dry it and check where it's coming from Wipe the cabinet thoroughly and look: is the water coming from the system itself, from the siphon, from the regular kitchen faucet, or from the dishwasher? Many leaks under the sink are not related to the water system. Have you identified that the source is not our water system?
- Film the source of the leak In the next step we'll ask you for a short video. Film the open cabinet with good lighting and, if possible, the exact point the water dripped from. This saves us a diagnostic visit and lets us arrive with the right part. Ready to continue to filming?
Unusual noise
- Identify when the noise is heard Is the noise heard only while you're drawing water, or also when you don't touch the faucet? Systems with a pump make a hum during operation — that's normal. Noise while idle is a different story. Is the noise heard only while drawing water and does it stop afterwards?
- Check whether the system is touching the cabinet wall The system vibrates slightly during operation. If it touches the wall, a pipe or an object in the cabinet — the vibration becomes a loud noise. Gently move whatever is touching it and check again. Has the noise stopped?
- Check whether it stops by itself Some systems perform a short automatic flush from time to time, even without you touching the faucet. It sounds like flowing water and stops by itself within less than a minute. Did the noise stop by itself within less than a minute?
Light or alert on the system
- Where the indicator appears Some models have lights on the system body under the sink, and some have an illuminated ring at the base of the faucet. Other models have no indicator at all. Check exactly where you see what has changed. Have you found the source of the indicator?
- Check what your model's instructions say The meaning of each colour varies from model to model, so it's not right to guess. If you kept the booklet or sticker that came with the system — that's where it says what each indicator means. On most models, an indicator that changes signals that a filter is nearing its end. Have you found the meaning and understood what's needed?
- If you replaced a filter and the indicator didn't reset On some models the indicator has to be reset manually after a filter replacement — usually by a long press on a dedicated button. If you replaced it recently and the indicator stayed on — it may just be the reset that's missing. Did the reset solve the problem?
Garbage disposal
Not responding at all
- Check the red reset button Most disposal models have a small reset button on the bottom, underneath — usually red. If the motor was overloaded it pops out and the unit stops working. Press it until it stays in. Before you touch the disposal — unplug it or switch off its breaker in the panel. Is the disposal working again?
- Check the power Make sure the plug is connected and that the breaker in the electrical panel hasn't tripped. If there's a dedicated wall switch for the disposal — make sure it's on. Is the disposal working again?
- Check the on button Some installations have an air button on the countertop. Press it fully and quickly. If it feels soft or sunken — it may be broken, and that's a fault we handle. Have you established that the fault is in the button?
Humming but not turning
- Switch it off immediately Humming without turning means something is jamming the grinding chamber. Leave the unit off — switching it on again could burn out the motor. Never put your hand inside the disposal. Not even when it's off. Have you switched it off?
- Disconnect the power Pull the plug out of the socket under the sink, or switch off the dedicated breaker in the panel. Have you disconnected it?
- Free it with the Allen key Most models come with a small Z-shaped Allen key, and the bottom of the unit has a hexagonal hole that fits it. If you don't have the key or your model has no such hole — stop here and don't improvise. Insert the key and turn it back and forth a few times until it turns freely. If you don't have the key — stop here. Does the key turn freely now?
- Remove the obstruction and switch on Look inside with a torch and remove whatever is stuck — with tongs or a spoon, not by hand. Reconnect the power, press the reset button on the bottom if your model has one, turn on the cold water and switch on. Is the disposal working again?
Leak
- Switch off and dry Switch off the disposal and wipe the cabinet thoroughly, so you can see where the water is really coming from. If water is flowing in quantity — close the water valve under the sink and call: 052-5958465 Have you dried it?
- Fill with water and check where it drips Plug the sink, fill a little water, and release it. Look underneath: is the water coming from the sink connection at the top, from the siphon at the side, or from the disposal body itself? Have you identified that the source is the siphon and not the disposal?
- Film the spot In the next step we'll ask for a video. Film the point the water dripped from with good lighting — this lets us arrive with the right seal the first time. Ready to continue to filming?
Loud metallic noise
- Switch it off immediately A metallic noise almost always means something hard has fallen in — a teaspoon, a bottle cap, a bone. Running it further will damage the grinding chamber. Never put your hand inside the disposal, even when it's off and disconnected. Have you switched it off?
- Disconnect the power and shine a light inside Unplug it or switch off the breaker. Look inside with a torch. Can you see something that has fallen in?
- Remove it with tongs Remove the object with long tongs or a spoon — not by hand. Reconnect the power, turn on the cold water and switch on briefly to check. Has the noise gone?
Bad smell
- Flush with cold water Turn on the cold water and run the disposal for about 30 seconds. Scraps stuck to the walls are the most common source of smells. Has the smell gone?
- Ice and coarse salt Put in ice cubes and a spoonful of coarse salt, turn on the cold water and run it. The ice scrapes and cleans the walls. Has the smell gone?
- Citrus peels Grind lemon or orange peels with cold water. This neutralises odours and leaves a clean smell. Has the smell gone?
- Check what goes into the disposal The disposal is designed for soft food scraps. Liquid fat in quantity solidifies in the pipes and causes smells, as do long fibres such as celery or corn husks. Running cold water while grinding helps fats move on instead of sticking. Have you understood what caused the smell?
Slow or blocked drainage
- Check whether the other side of the sink is also slow If you have a double sink and both sides are slow — the blockage is in the shared pipe, not the disposal. Is the other side slow too?
- Run it with a strong flow of cold water Turn on a strong flow of cold water and run the disposal for 30 seconds. Sometimes piled-up scraps move on. Has the drainage improved?
- Don't use drain-unblocking chemicals Chemical drain unblockers damage the seals and metal of the disposal and can turn a small fault into an expensive one. If you've got this far — it's better that we handle it. Understood, and you haven't used chemicals?
