Hotpoint Aquarius Dishwasher Flashing Lights Code: Your Ultimate Fix-It Guide”
You’ve just loaded your Hotpoint Aquarius dishwasher, ready for it to take on the dirty work, when suddenly the control panel lights up like a Christmas tree. Flashing lights can stop you in your tracks, turning a routine chore into a troubleshooting mission.
But don’t worry those blinking indicators are your dishwasher’s way of crying for help, and they’re not as mysterious as they seem. Whether it’s a model like the FDL570 or FDM550, this common issue has a range of causes, from simple fixes to trickier repairs.
In this comprehensive guide, we’ll break down why those lights are flashing, what they might mean, and how to get your dishwasher humming again. Packed with practical steps and insights from real users, let’s turn off the chaos and turn on the clean!

Why Are the Lights Flashing?
When your Hotpoint Aquarius dishwasher starts flashing its lights, it’s not just putting on a show it’s signaling a problem. These appliances use light patterns to communicate faults, much like a car’s dashboard warning lights.
A blinking “start” light might mean the cycle can’t begin, while flashing “salt” and “rinse aid” lights often accompany other indicators to highlight an error code.
Power disruptions are a frequent trigger, scrambling the electronics and leaving lights blinking. A misaligned or broken door latch can also halt the process, flashing a warning. Water troubles like a blocked inlet or a drainage snag often set off specific patterns, as does a malfunctioning part like the heater or pump.
In some cases, chaotic flashing of all lights points to a control system meltdown. The trick is to watch the sequence and match it to what’s happening with the machine to narrow down the cause.
Top Causes and Solutions
Here’s a deep dive into why your Hotpoint Aquarius dishwasher’s lights are flashing—and how to fix them.
1. Electronic Reset Needed
A power blip can confuse your dishwasher, causing lights like “on/off” or “wash” to flash erratically.
- Solution: Unplug the unit or switch off the breaker for a few minutes. Power it back up and try starting a cycle. This often clears the glitch.
2. Door Not Secured
If the door isn’t latched, the dishwasher won’t run, and lights like “start” or “end” might blink to alert you.
- Solution: Open the door, check for blockages, and close it firmly. If the latch is damaged, it might need replacing either a DIY job or one for a pro.
3. Water Inlet Blockage
No water flow can stop the cycle, often flashing “salt” or “rinse aid” lights alongside others.
- Solution: Ensure the water tap is on and the inlet hose isn’t kinked. If water still doesn’t enter, the inlet valve might be clogged or broken, requiring a replacement.
4. Drainage Failure
A clogged filter, hose, or pump can prevent draining, triggering lights like “wash” or “dry” to flash.
- Solution: Clean the filter inside the dishwasher and inspect the drain hose for blockages. If drainage fails, the pump might need a new part (around $50-$100).
5. Specific Error Codes
Hotpoint Aquarius models often use light patterns as error codes. For example, “salt,” “rinse aid,” and “wash” flashing might mean a heater issue, while “on/off” and “end” could signal a pump fault.
- Solution: Record the pattern and check your manual or Hotpoint’s site. A heater problem might need a multimeter test, while a pump issue could require expert help.
6. Control Panel or Board Issues
If all lights flash or the panel’s dead, the touchpad or control board might be failing a common headache in older units.
- Solution: Reset first. If that flops, test the buttons. A bad touchpad costs $50-$150 to replace, while a control board fix might hit $200 with labor.
How to Troubleshoot the Problem
Let’s tackle those flashing lights with a clear plan:
- Power Down: Unplug the dishwasher or cut the breaker for 2-3 minutes, then restart it to see if the lights settle.
- Secure the Door: Open it, clear any obstacles, and shut it tight. Hit start right after closing.
- Check Water Supply: Confirm the tap’s open and the hose is free. Start a cycle and listen for water.
- Clear the Drain: Remove the filter, wash it clean, and check the drain hose. Test with a short cycle.
- Interpret the Lights: Note which lights flash and how often, then look up the pattern in your manual or online.
- Test the Controls: Press each button to check responsiveness. Sticky ones might mean a panel fault.
- Call for Backup: If the lights won’t quit, contact Hotpoint (0344 822 4224 in the UK) or a repair tech.
When to Call a Technician
Some issues need more than a home fix. If resetting doesn’t stop the flashing, or if you spot leaks, odd sounds, or all lights going haywire, a professional’s your best bet.
A control board failure or pump problem could be the root, with repairs ranging from $100-$300. If your dishwasher’s under warranty, reach out to Hotpoint first to keep it covered. A technician can diagnose complex faults quickly, saving you time and hassle.
Tips to Avoid Flashing Lights
Stop trouble before it starts with these habits:
- Clean the filter monthly and run a vinegar cycle to prevent clogs.
- Inspect hoses and the latch for wear regularly.
- Load dishes without crowding the spray arms.
- Use a surge protector to shield the electronics.
- Always latch the door properly before running.
