Water is just as crucial to your Dolce Gusto’s operations as coffee beans. Therefore, you have every reason to worry when the water stops coming out. Many people blame the following factors for this outcome:
1). Does The Machine Have Water?
This sounds ridiculous, but it can happen. The water won’t flow if you forget to add water to the unit. Check the reservoir before you panic and hire an expert. Your technician of choice may charge you a consultation fee even after realizing that you simply forgot to add water.
2). Blocked Capsule
This Dolce Gusto JOVIA manual blames this issue on a blocked capsule. You should also check whether the capsule is under pressure.
Look for leaks. Leaks can occur because water can’t enter or leave the capsule. You will see the water escaping from the capsule holder’s sides instead of flowing into your mug. If the water starts flowing, you may observe a lower pressure than expected.
Some people blame this issue on broken injection nozzles resulting from mishandling. For instance, the nozzles can bend or break off as you load the capsules. Others blame this issue on a clogged nozzle. Look for calcification.
If fortune has turned against you, the capsules may develop permanent defects. This assumes that the capsules you bought were the correct size for the machine. It may take extensive troubleshooting to find the source of the leaks. They won’t appear in places where you can see them easily, precluding elements such as a broken water tank.
4). Blown Fuse
People typically blame a lack of flowing water on blockages. They don’t realize that a Nescafe Dolce Gusto unit requires power to pump water to its destination. In other words, the absence of a working power supply can stop the water from flowing.
Check the pump’s fuse. The fuse blows when it encounters an overload. You can test it for continuity with a multimeter to confirm your suspicions.
If the fuse is okay and the machine has power, but the water refuses to flow, the pump has a fault. This can happen because of a factory defect, clogging, or damage caused by poor handling, surges, and the like.
You should talk to an expert. If you have the money, you may attempt to replace the pump even though a technician can fix it.
How To Fix Nescafe Dolce Gusto That Won’t Pump Water?
You must start by troubleshooting the machine. Once you identify the culprits, you can deploy the following solutions:
1). Clean The Nozzle
If the water is seemingly flowing, but the machine won’t dispense your coffee, the nozzle is blocked. You should clean it. This involves the following:
- Stop the machine and pull the plug out of the outlet.
- Remove the water tank and find the battery maintenance spring. This element is easy to identify because it matches the size of the nozzle. But if you can’t locate it, check the manual for further instructions. Maybe your unit did not come with a spring. These mistakes happen all the time. But this means talking to an expert. They have the relevant tools.
- Push the spring into the nozzle to remove obstructions. You have to move it back and forth until the nozzle is clean.
- Put the spring and tank back. Add water to the tank and turn the machine on. Run it to see if the water will flow.
2). Don’t Run The Coffee Maker Without Water
You can harm the pump by running the coffee maker without water. This introduces air, which, in turn, reduces the water pressure. Fortunately, the solution is relatively straightforward:
- Take the tank out and fill it with water.
- Put the tank back.
- Remove the tank.
- Put it back.
Do this procedure dozens of times. Along the way, you will see bubbles rise from the tank. Eventually, all the air will escape. You can test the results of your hard work by turning the unit on and seeing whether or not the water flows.
If you don’t have the time or patience to perform this procedure, leave the machine alone for the next few hours. The air will slowly escape.
You can also perform series of steps for testing the water pump. It involves connecting the hose from the pump outlet to the water tank. A healthy pump will pump water, proving that it still works.
If the pump fails this test, talk to the manufacturer’s customer support team about getting a replacement. Use your warranty. Although, you may fix the component by gently tapping the pump with a suitable tool while turning the unit on and off. This can remove obstructions.
3). Fix The Malfunction
Various components in a coffee maker can malfunction, besides the pump. They include the following:
- Thermoblock – Water circulates through the thin channel inside this metal alloy. If the thermoblock breaks or deforms, the water won’t circulate at the correct speed. You can’t diagnose the thermoblock without disassembling the machine.
- Control Board – The control board runs everything. Therefore, a defective control board will attract all kinds of malfunctions. A technician can fix or replace it.
- Hot/Cold Selector – Use the multimeter to perform a continuity test on the selector switch. If the selector switch is dead, replace it.
Descale the machine once every three months. Without routine descaling, the unit will continuously clog or leak. Use soda bicarbonate to clean a blocked delivery pipe.
5). Replace The Blown Fuse
The only solution to a blown fuse is to replace it. You don’t fix these items. You must disassemble the unit, a procedure laypeople should avoid unless they have experience with these devices.
You need a multimeter to test for continuity. If there’s no continuity, find a replacement that matches the dead fuse.
6). Replace Broken Injector Nozzles
Every damaged injector nozzle isn’t necessarily broken. Look at the extent of the damage. A bent nozzle is salvageable. Bend it back gently and carefully. The metal is brittle enough to break if you apply excessive force.
If the nozzle is genuinely broken, you must replace it. Do the same for defective capsules. Make sure the size matches the demands of the Nescafe Dolce Gusto unit.
How Much Does It Cost To Fix Nescafe Dolce That Don’t Pump Water?
You don’t have to spend any money to unclog or descale the device. However, you must buy replacement parts when a vital component breaks. New injector nozzles, control boards, and pipes could cost you hundreds of dollars depending on the recommendation the manufacturer has made for your particular situation.
