The Miele Dishwasher F70 Fault Code: What It Means and How to Fix It!
Uh-oh did your Miele dishwasher suddenly stop mid-cycle and flash the dreaded “F70” error code at you? Don’t worry, you’re not alone, and more importantly, you’re in the right place! This error can feel intimidating, but I promise it’s not as scary as it seems. With a little guidance, you could be well on your way to enjoying spotless dishes again in no time!
What Does the Miele Dishwasher Fault Code F70 Mean?
The F70 error code on a Miele dishwasher signals a safety feature activation called the “Watersafe System”. Basically, it means your dishwasher’s leak detection system has detected water where it shouldn’t be inside the base of the appliance. This could be due to a small drip, an overfilled unit, or something as simple as an improperly closed door.
Think of it as your dishwasher’s way of saying, “Hey, something’s not right! Help me out here!”
But don’t panic! Most of the time, this error can be resolved without calling in the professionals.

How to Fix the F70 Error Code
Here’s a step-by-step guide you can follow to troubleshoot the issue. Before you start, turn off the power to your dishwasher for safety. Better safe than sorry, right?
Step 1: Check for Obvious Leaks
The F70 can trigger if any water has made its way into your dishwasher’s base.
- Check the door seal are there any gaps or signs of wear? If water leaked from the front of the door, it could just be a faulty seal.
- Inspect the hoses look at both the inlet and drain hoses for kinks or damage. A loose fitting could cause water to seep into the base.
If you spot any leaks, fix or replace the damaged parts before moving on to the next step.
Step 2: Drain the Dishwasher’s Base
Excess water in the base of your dishwasher can fool the Watersafe System into thinking there’s a major leak. Time to say goodbye to that water!
- Remove the bottom panel (you may need to unscrew it!).
- Use a sponge or towel to mop up any standing water in the drip tray located at the base of the dishwasher.
- A small trickle? Tilt the dishwasher slightly forward just be careful and make sure you have a towel ready to catch the drips.
Step 3: Dry Everything Out
Once the water is removed, give your dishwasher’s internal parts time to dry off completely. Pro tip? Use a hairdryer on a low-heat setting to speed things up if you’re in a hurry!
Step 4: Restart the Dishwasher
After everything is dry and clean, switch the power back on and run a test cycle. Voila! Most of the time, this will resolve the issue.
Bonus DIY Checks (if the above didn’t work!):
- Clogged Filters – Clean the dishwasher filters. A clog can cause water buildup, so check for food debris blocking the drain.
- Blocked Drain Pump – If draining is slow, inspect the pump for anything that might be stuck (like a stray olive pit thanks, pasta night! 🍝).
- Overloading – Overloading your dishwasher can cause water to splash into the base. Run lighter loads and give those dishes some room to breathe.
When to Call in a Professional
If you’ve tried all the steps above and that pesky F70 code keeps flashing, it might be time to call in the pros. There could be a more complex issue such as a damaged float switch or a worn-out water inlet valve. Don’t stress professionals can usually fix these problems quickly!
How to Prevent the F70 Error in the Future
