Ariston dishwasher won't turn on

It's a very frustrating situation when you're just about to wash another pile of dirty dishes, and your Ariston dishwasher won't turn on. This can happen to any dishwasher, regardless of model or brand. Why this happened to your appliance, and what you can do about it, we'll explain in detail in today's article.

Let's start the diagnostics with the simplest thing

Most housewives have absolutely no idea what to do in such a situation, so they panic. However, the absence of obvious "signs of life" from a dishwasher is not a reason to order a complex and expensive repair. First, open the wash chamber door and carefully inspect the machine's control panel. If none of the lights or indicators are illuminated or even blinking, the dishwasher may not have power, so the simplest thing to check is the one that's most likely dead.

• Electricity. The problem could be in your home or area of ​​the city where the power went out without you even noticing. A tripped circuit breaker is also possible and should also be inspected.
• The outlet. The outlet itself may be faulty, which is common in older homes because the "ancient" wiring simply can't handle the power of modern appliances. The easiest way is to plug another electrical appliance into the outlet to confirm that the fault lies with the outlet and not the dishwasher.

You can also check the outlet with a multimeter, which will accurately show the voltage. Sometimes, the outlet is perfectly fine, but its power is simply insufficient to run a power-hungry device due to poor wiring.

• Power cord and plug. Finally, check the power cord, as it's often the source of the problem. If you find damage to the cord, don't even try to repair it—it's best to replace the entire component immediately to avoid a short circuit and fire caused by a poorly repaired cord.

The last point is especially important because it is very easy to damage the wire without noticing it. Copper wires in the power cord are often damaged because dishwasher owners accidentally crush the element while carelessly placing the machine directly on it, which is definitely not something to do.

The fault is hidden inside the dishwasher

In the first section, we covered the most common causes of malfunction, but also the most harmless and requiring the least complex repairs. Now it's time to discuss serious hardware and software issues, which are almost impossible to resolve without professional training and experience. However, if you're confident enough to handle the problem yourself without a service center, then we'll outline the likely cause of your dishwasher's breakdown.

• The thermal fuse has blown. This component is responsible for shutting off the dishwasher in the event of overheating. If this fuse fails, the machine simply won't start. You can check the functionality of the part using the same multimeter. A faulty element must be replaced immediately.

Do not buy a new fuse until you have removed the damaged unit, which you should take to the store as an example to purchase an identical one.

• The recirculation pump capacitor has failed. This component circulates water throughout the wash chamber. Capacitor damage is usually caused by power outages, sudden power outages, and sudden voltage surges. For an accurate diagnosis and subsequent replacement, the dishwasher will need to be partially disassembled. However, other signs that it's broken can also be identified by weak water pressure from the spray arm and poor dishwashing.
• The recirculation pump impeller is clogged. In this case, the pump won't work properly simply because the impeller has become jammed after being filled with food debris, bones, tea bags, and other debris that shouldn't be in the wash chamber.
• The power button is broken. It could have broken due to prolonged use or exposure to moisture, causing the dishwasher to simply not turn on. To check, remove the button from its housing, test it with a multimeter, and replace it if it's damaged, or if its contacts are burnt out or corroded.
• The surge protector is damaged. This is especially true if your "home assistant" is not connected directly to the power grid, but through a surge protector. If it is truly damaged, it must be replaced. A broken surge protector is not worth even attempting to repair, as after repair, it will no longer protect your devices from poor electrical power, making it completely useless.
• The door lock is broken. If the door no longer closes tightly without a distinctive click, the appliance will simply not operate. In this situation, the lock mechanism must be replaced, which requires removing the bolts, removing the locking panel, and replacing it with a new one.

But the worst option is with a damaged dishwasher control unit. The electronic module is an expensive component of the dishwasher that can fail due to moisture and power outages. If the problem is with this unit, you won't be able to repair it yourself – you'll have to call a technician who will perform the following steps:

• removes the dishwasher door and retaining bolts;
• remove the control unit of the machine;
• will check the module carefully;
• will restore damaged parts or immediately install a new unit.

DIY repairs are commendable and cost-effective, but you should only resort to them if your appliance's warranty has expired. Otherwise, you should always use the warranty to ensure high-quality repairs are free of charge.
