Miele Dishwasher Troubleshooting – Common Problems to Fix!
Below are the eight issues common with your Miele dishwasher:
1. Miele Dishwasher Won’t Turn On
After loading your Miele dishwasher, it’s frustrating to discover that it won’t turn on. Below are the reasons to explain why this happens and the fixes to perform:
- Open door – If the door is slightly open, your dishwasher won’t start.
- Insufficient water – Water is essential in cleaning the dishes. If your dishwasher doesn’t receive enough water, the wash cycle won’t start even after pressing the start button.
- Active lock controls – If child lock is active, your dishwasher won’t start. Also, if the delayed start function is on, it tells your dishwasher to start later. Do not also forget to check the sleep mode function. When it’s on, your dishwasher won’t start either.
- Power issues – If there’s a power outage, your dishwasher won’t start. Also, your dishwasher won’t start if the thermal fuse or circuit breaker blows up.
Quick Fix
Latch the door, and if the latch is damaged, replace it. Ensure enough water flows to your dishwasher, turn off active lock controls, and fix power issues.
2. Miele Dishwasher Won’t Drain
A dishwasher should drain after each wash cycle. If your dishwasher doesn’t drain, below are the reasons to explain why:
- Clogged filter – The filter is the first culprit to check when your Miele dishwasher fails to drain. Over time, the filter can clog with food residues, and when this happens, water won’t drain or may drain slowly.
- Obstructions in the drain hose – If the hose is clogged, has bends, kinks, or twists, the dishwasher will have difficulty draining or may not drain at all. Also, if the hose is too short or long, there won’t be flawless drainage.
- Defective impeller – If there’s no clogging on the hose, pump, or filter, the impeller should be your next check. If it pulls without resistance, it could have stripped, which explains why your dishwasher fails to drain.
Quick Fix
Unclog the heavily clogged filter by washing it in running tap water with mild detergent, remove any obstructions from the hose, and try straightening it out if it has bends, twists, or kinks. Lastly, replace the impeller if faulty.
3. Miele Dishwasher Won’t Wash – Troubleshooting
The purpose of a dishwasher is to clean and dry the dirty dishes. What a shame to find out that your dishes are still soiled after a wash cycle ends. Below could be why your dishwasher fails to wash the dishes clean:
- Using too much detergent – Detergent is essential in cleaning utensils. However, using the wrong detergent or too much of the correct detergent forms suds that may accumulate on the dishes.
- Wrong settings – Another apparent reason why your Miele dishwasher won’t wash is due to selecting the wrong setting. For instance, you may have chosen a Quick Wash or Rinse Only setting for heavily soiled dishes, which is not powerful enough to clean your dirty dishes.
- Improper dish load – When loading your Miele dishwasher, the soiled surfaces should face toward the spray arms. If that’s not the case, the dishes won’t wash clean.
Quick Fix
Use the right detergent (according to the manufacturer’s instructions) and in the proper proportions. Remember to choose the correct settings according to how dirty the dishes are and the load size, and lastly, ensure you load your dishwasher correctly.
4. Miele Dishwasher Leaks
When you find water on your kitchen floor when the dishwasher is running, the likelihood of your dishwasher leaking is high. If that’s the case, then your dishwasher leaks due to the following:
- Broken Door Seal – Since it’s rubber, your dishwasher seal may have broken. It may also loosen over time, thus not giving an airtight seal to your dishwasher.
- Using much detergent – Using much detergent, especially the wrong type, creates suds that require much water to rinse. The excess water may leak, which could be why your kitchen floor is wet.
- Dishwasher overload – Once you overload your dishwasher, it will require much water, which may cause an overflow that could lead to a leakage.
- Improper installation – If the installation is wrong where there’s a poor connection between the water supply and the drain system, then water may sip to your kitchen floor.
Quick Fix
Check the seal for any physical sign of damage, wear, or loose, and replace it. Ensure you use the right detergent in proportions and do not overload or nest the dishes so close.
5. Miele Dishwasher Control Panel Not Working
Another problem you can troubleshoot is when the control panel becomes unresponsive. When that happens, below are the checks to make:
- Defective control board – If the control board is bad, your dishwasher control panel won’t respond to any command.
- Blown thermal fuse – The thermal fuse prevents your dishwasher from any electrical damage. The control panel won’t respond to commands if the fuse blows up due to a power surge.
Quick Fix
Test the control board’s and thermal fuse’s continuity and replace the part that shows no continuity.
6. Miele Dishwasher Not Drying Dishes
You expect your dishes to dry after a drying cycle completes. Well, this is not always the case. If you get wet dishes, you should check the following:
- Defective heating element – The heating element produces heat that helps dry the dishes. If it’s faulty or has blown out, your utensils won’t dry.
- Wrong setting selection – To humans is to error. We all sometimes select the incorrect settings unintentionally. When this happens, your dishes won’t dry.
Quick Fix
Test the heating element continuity and replace it if it shows no continuity. If the dishes don’t dry due to the wrong setting, select Heated Dry or Rinse Aid setting for the dishes to dry.
7. Miele Dishwasher Won’t Fill with Water
For spotless clean dishes, three things are essential. They include water, power, and detergent. Without one of these, no washing will take effect.
If your dishwasher doesn’t fill with water, check the following:
- Obstructed water line – Debris, dirt, and dust can build up in the water line over time. It could also be that the line is damaged.
- Turn off supply line – If your home water supply line is off, your dishwasher won’t get water.
Quick Fix
Clear any obstructions from the water line. If the supply line is off, turn it on for water to flow to your dishwasher.
8. Miele Dishwasher Door Won’t latch
Another common Miele dishwasher problem is unlatching doors. When the door doesn’t latch, the wash cycle can’t commence. Below are the reasons why your Miele dishwasher door fails to latch:
- Stuck items – check if small utensils like knives, forks, or spoons protrude from the dishwasher.
- Broken latch – If the latch has cracks or physical damage, there is no doubt that it won’t close as it should.
- Unleveled dishwasher – If the dishwasher is not standing on level ground, it may be a problem latching it. It may also latch falsely, which will make the dishwasher not start.
Quick Fix
Remove any item protruding from the dishwasher, replace a broken latch, and ensure the dishwasher stands on level.
