Common Ariston Washing Machine Problems

Understanding the symptoms of a faulty Ariston washing machine helps you communicate clearly with a technician, attempt safe DIY fixes, and avoid making the problem worse. Below are the six most frequently reported issues.

Washing Machine Not Draining

Drainage failure is the single most reported Ariston washing machine problem in the UAE. Water remains in the drum after the cycle ends, the machine stops mid-cycle, or you hear the pump struggling to empty the tub.

• Most likely cause: Blocked drain pump filter. The filter is located behind a rectangular access panel at the bottom-front of the machine. Lint, coins, hair clips, and small garments collect here over time and choke the pump.
• Related error codes: F05 (pressure switch stuck on full / drain fault), F11 (pump not responding), F15 (drain pump fault on standard range).

DIY fix: Place a shallow tray and towel beneath the access panel. Slowly unscrew the filter cap to let water drain. Remove all debris, rinse the filter under a tap, and replace. Run a short 30°C cycle to confirm the fault has cleared. This fix resolves the majority of drainage faults with no parts or cost.

Washing Machine Not Spinning

The drum fills and washes but will not reach spin speed, or the spin cycle starts then cuts out. Wet, heavy laundry sits unspun at the end of the cycle.

Most likely causes: Overloaded drum, faulty motor brushes, worn drive belt, or a motor triac fault on the PCB (control board).

Related error codes: F01 (motor triac short circuit), F02 (motor jammed or tacho sensor detached), F30/F31 (motor drive fault on standard range).

DIY fix: Reduce the load to no more than three-quarters of the drum capacity. Redistribute laundry evenly and restart the spin cycle. If the fault code persists after a reset, the motor or PCB requires a qualified engineer.

Washing Machine Not Filling with Water

The machine powers on and the cycle begins, but the drum never fills. You may hear a buzzing from the inlet valve, the cycle runs dry, or an H20 error appears on the display.

• Most likely causes: Water tap turned off or partially closed, kinked inlet hose, blocked inlet valve mesh filter, or insufficient water pressure.
• Related error codes: H20 (direct water supply warning), F10/F11/F12/F13 (fill-related faults on standard range), F04 (pressure switch empty fault on EVO1/EVO2).

DIY fix: Fully open both the hot and cold taps behind the machine. Check the inlet hoses for kinks. Disconnect the hoses and clean the small mesh filter screens inside each fitting using a toothbrush and diluted white vinegar.

Washing Machine Door Won’t Open or Lock

The door refuses to unlock after the cycle, or the machine won’t start because it cannot detect that the door is properly locked.

• Most likely causes: Faulty door interlock switch, worn door seal trapping the latch, or a drainage issue preventing the safety lock from releasing (the machine keeps the door locked while water remains in the drum).
• Related error codes: F17 (door interlock error on EVO2/V4), LOCKED display on EVO1 models.

DIY fix: Wait two minutes after the cycle ends for the thermal interlock to release. If the door remains locked, check whether water has drained completely. If drainage is clear and the door still won’t open, the interlock switch requires replacement by a technician.

Washing Machine Leaking Water

Water pools beneath the machine during or after a cycle. This can indicate a simple seal issue or, in more serious cases, a cracked drum or failed pump housing.

• Most likely causes: Worn or torn door seal (gasket), loose drain hose connection, overfilling caused by a faulty inlet valve, or a cracked pump body.
• DIY check: Inspect the rubber door gasket for visible cracks or mould damage. Check that the drain hose connection at the back of the machine is secure and not cracked. Do not operate a leaking washing machine as water damage to the motor or PCB will escalate repair costs significantly.

Excessive Vibration or Loud Noise

Ariston washing machines are known for quiet operation, so unusual vibration or banging during the spin cycle indicates a mechanical fault.

• Most likely causes: Overloaded drum, laundry bunched on one side, worn drum bearings, damaged shock absorbers, or a foreign object caught between the drum and the outer tub.

DIY check: Ensure the machine is level on the floor using a spirit level and adjust the levelling feet if needed. Reduce load size. If noise continues, the drum bearings are likely worn and will require a technician, bearing replacement is a complex repair requiring partial disassembly of the machine.

Complete Ariston Washing Machine Error Code Guide (All Series)

Ariston washing machines use three distinct error code systems depending on the model series. Identifying your model series first will ensure you interpret the code correctly.

Standard Range Error Codes

These codes apply to Ariston washing machines without an LCD display.

DIY Troubleshooting Before You Call a Technician

The following steps resolve the majority of Ariston washing machine fault codes and cost nothing. Work through them in order before booking a repair visit.

Step 1: Perform a Hard Reset

Turn the machine off at the mains wall socket and leave it unplugged for 60 seconds. Plug back in and restart. A hard reset clears temporary error flags stored in the control board memory. If the same code returns after a reset, the underlying fault is real and needs to be addressed, but many codes are caused by one-off power fluctuations and will not return.

Step 2: Clean the Drain Pump Filter

The drain pump filter is the single most common cause of fault codes on Ariston washing machines, and cleaning it takes under 10 minutes. The filter is located behind a small rectangular access panel at the bottom-front of the machine.

• Place a towel and shallow tray beneath the panel
• Unscrew the filter cap slowly to let water drain into the tray
• Pull out the filter and clear all lint, coins, and debris by hand
• Rinse under running water and screw back into place
• Run a short 30°C cycle to confirm the fault has cleared

Clean this filter every 1-2 months. This single action resolves F05, F11, and F15 in the vast majority of cases.

Step 3: Check the Water Taps

Fully open both the hot and cold water taps behind the machine. A partially closed tap is the most common cause of H20, F10, F11, and F12 error codes. After opening the taps, run a short cycle to confirm the issue is resolved.

Step 4: Clean the Inlet Valve Mesh Filters

Remove the inlet hoses from the back of the machine. Inside each hose fitting is a small mesh filter screen that collects limescale and debris, restricting water flow. Clean with a toothbrush and diluted white vinegar, rinse thoroughly, and refit the hoses securely.

Step 5: Check Drain Hose Height

The drain hose standpipe must be raised to at least 40-50cm from the floor. If the hose sits too low, the machine syphons water out as fast as it fills, triggering fill-related fault codes repeatedly. Use the hose guide clip supplied with the machine to secure it at the correct height.

Step 6: Balance the Load and Check Level

Redistribute laundry evenly around the drum and reduce the load size. Confirm the machine is level using a spirit level and adjust the four levelling feet as needed. Rebalancing the load resolves most vibration and mid-spin error codes without any repair.

Step 7: Close the Door Firmly

Push the door shut until you hear and feel a definite click. Check that no clothing is trapped in the rubber door seal. On EVO2 and V4 models, the door must engage the latch fully before the interlock activates and the cycle can begin

When to Call a Professional for Ariston Washing Machine Repair

Some faults are beyond safe DIY repair. You should contact a certified Ariston technician immediately when:

• An error code returns after a hard reset and the DIY steps above have not resolved it
• You suspect a PCB or control board fault (F01, F07, F08, F09, F18)
• The machine is leaking and the source is not the drain hose or filter
• There is burning smell, sparks, or signs of electrical fault
• The drum is not rotating at all after load rebalancing
• The machine is flooding or showing a persistent high-water-level warning
• Drum bearings are worn, partial disassembly is required

Attempting PCB and wiring repairs without proper training is dangerous and can void your repair warranty. For all the above, professional service is the right call.
