Gaggenau Dishwasher Not Draining

---

In short, a Gaggenau dishwasher not draining may typically result from two main causes – clogs and blockages or mechanical failures.

---

Clogs and blockages

Typically, clogs and blockages may be caused by food debris, grease, or glass fragments. While you can easily address some blockages yourself, other issues may require professional Gaggenau dishwasher repair.

Clogs and blockages you can address yourself

At LE Company, we build the list of issues to check first if your Gaggenau dishwasher is not draining:

• Clogged filters (at the bottom of the tub)
• Clogged drain pump impeller (underneath the filter)

​To troubleshoot the clogged filter, pull out the filter and wash it with warm soapy water. To troubleshoot the clogged drain pump impeller, reach in with tweezers to pull out blocking glass fragments or food debris.

Clogs and blockages to turn to professional service

Apart from a clogged filter or drain pump impeller, there could be more severe issues for a Gaggenau dishwasher is not draining:

• Clogged check valve (the valve that prevents backflow)
• Clogged drain hose (the hose connected with the sink drain or garbage disposal)
• Clogged or jammed drain valve (the valve that opens to release water)

​Typically, at LE Company, it takes us 15 – 30 minutes to troubleshoot the clogged drain hose and 20 – 40 minutes to troubleshoot an issue with the check valve. A clogged or jammed drain valve requires more extensive disassembly. Typically, it takes us 1 – 1.5 hours to fix this issue.

Mechanical failures

Mechanical failures are the most severe issues. Addressing such failures is not a DIY task but requires professional assistance.
​
At LE Company, we build a list of common mechanical failures that lead to drainage problems:

• Broken drain impeller (can’t physically push water out of the dishwasher)
• Burned pump motor (drain pump not working at all)
• Faulty control board (can’t send power to the drain pump)
• Faulty drain solenoid (can’t open the drain valve)

Typically, in all these cases, the component needs replacement. Fortunately, with the component in stock, our engineer can fix any of these issues just in one go.

Conclusion

To summarise, a Gaggenau dishwasher not draining is typically caused by either clogs and blockages or mechanical failures.
​
Minor issues, such as a dirty filter or a blocked drain pump impeller, can often be resolved with simple DIY cleaning. A clogged drain hose, check valve, or drain valve are more complicated problems and require professional attention. The most serious cases involve mechanical component failures (a broken impeller, burned-out motor, faulty control board, or defective solenoid) and almost always demand part replacement by a qualified technician.
