Parts required
Senior moment. Had the no drain Issue on my LG F12u1tcn4. Stripped it down to clean but appear to have lost the L/H side of the pump ( Viewed from the front) which is two wire from the machine so I belive only one pump which I have on the R/H side. What goes on the L/H side. Also the smaller diameter black hose is missing from the pump. Where does it go to? Speaking to LG support all they can now offer is an engineer visit. Decided to cut my losses and buy a new machine but would like to complete the repair and sell as referbished. Thanks

It sounds like you’re looking at the twin-outlet drain pump housing and have misplaced one side of the assembly rather than a second separate “main” pump. On many LG washers of this type there is one drain pump motor, with the housing arranged to handle the main drain path and a small auxiliary connection.
Before doing anything else, isolate the washing machine from the mains.
1. Check the pump housing layout carefully From the front, the right-hand side is often the actual pump motor. The left-hand side may be the filter/pump body section or a blanking/guide part depending on the exact version. If you’ve “lost the left-hand side”, compare the pump body against exploded parts diagrams for your exact model number, including any suffixes.
2. Look for the missing small black hose connection The smaller hose is commonly the emergency drain/filter housing hose or a pressure/recirculation-related hose, depending on design. It should connect to a small spigot on the pump/filter housing or nearby sump assembly. Check for an unused small nozzle on: - the pump/filter body - the bottom of the tub/sump hose area - the front filter housing
3. Use the full model number to identify parts Search using the complete LG model and serial/product code on UK spares sites such as eSpares, BuySpares, or Partmaster. Exploded diagrams are often more useful than LG phone support.
4. Don’t guess and run it If any hose or pump section is missing, it will likely leak badly when draining.
If you can post a clear photo of the pump area, it should be possible to say exactly what is missing. For any internal wiring checks or fitting parts around live components, use a qualified appliance engineer.

Safety first — read before actioning advice
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional — do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts are full of sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you're not confident testing or working inside the appliance, STOP and call a professional.
