Today, we are looking at a very common issue that, if handled incorrectly, can completely write off your washing machine. We are working on a Hotpoint NSWF 742U washing machine manufactured around 2020, but this design flaw applies to many modern machines.

The machine in our workshop is mechanically perfect the bearings are smooth, the motor runs beautifully, and the electronics are flawless. Yet, it was headed for the landfill. Why? Because the customer washed something heavy (likely trainers) and snapped the plastic drum paddles (also known as lifters) off the inside of the drum.

Changing a drum paddle should be a simple DIY job. However, manufacturers have made it exceedingly difficult by sealing the outer tubs and hiding the metal retention lugs. The original owner tried to force new paddles into place without knowing how the locking mechanism worked, snapping the internal metal tabs. Because the drum is a sealed unit, breaking those tabs makes securing new paddles nearly impossible.

In this guide, I will walk you through exactly how these paddles are secured, how to remove them safely, and how to lock your replacements in place without breaking your machine.

Understanding the Hidden Locking Lug

If you look at a replacement drum paddle, you will notice plastic sliding clips along the bottom. However, the paddle does not just click into place.

Inside the metal drum, beneath where the paddle sits, there is a small, bendable metal tab (the retention lug). When the washing machine is assembled in the factory, the paddle is slid into place, and that metal lug is bent upright at a 90-degree angle to lock into the plastic paddle.

If you try to rip a broken paddle off, or force a new one on without dealing with this metal lug first, you will snap the metal tab flat off the drum. Once that tab is gone on a modern sealed drum, you have a massive problem.

How to Safely Remove a Broken Drum Paddle

Before you pull the old paddle away, you must flatten that metal lug to release the lock.

  1. Locate the access hole: Look at the top of the drum paddle. You will see a series of small holes. On this Hotpoint model, the locking lug sits directly beneath the 5th hole back from the front (on some older machines, it is the 6th hole).
  2. Push the lug down: Take a long, thin flat-blade screwdriver or a sturdy pin punch. Insert it into that 5th hole. You will need to feel around until you hit the metal resistance of the lug.
  3. Flatten the tab: Push down firmly until you feel the metal tab bend flat against the drum. Do not push too hard or you might bend it completely out of shape.
  4. Remove the paddle: Once the lug is flat, the paddle will easily slide backwards and lift away.

How to Install and Lock the New Drum Paddle

This is where the manufacturer’s sealed drum design makes life difficult. You slide the new paddle into place, but how do you bend that metal lug back up to lock it when the paddle is covering it?

There are two methods an engineer will use:

Method 1: The Hook-Nose Screwdriver (Recommended)

You will need a specific tool for this: a hook-nosed screwdriver which is essentially a thin shaft with a 90-degree bend at the tip (Amazon affiliate link for a hook screwdriver).

  1. Slide the new paddle firmly into its locked position.
  2. Carefully insert your hook-nosed screwdriver down through that same 5th hole.
  3. Feel around for the flattened metal lug.
  4. Hook the underside of the lug and firmly pull it up until it sits at a 90-degree angle, locking inside the plastic paddle.

Method 2: Access via the Sump Hose

If you do not have a hook tool, or you cannot get the leverage, you have to go in from the bottom.

  1. Unplug the machine from the electricity and empty any residual water.
  2. Carefully tilt the machine backwards.
  3. Remove the black rubber sump hose from the bottom of the outer tub.
  4. Reach up through the hole in the bottom of the tub, locate the metal lug beneath the paddle, and push it up into place using a screwdriver or pliers. Note: This is an incredibly awkward job, but it works. You can see how to do it on our video above.

What to Do If the Metal Lugs Are Already Broken?

If you are reading this too late and the metal tabs are already snapped off, you are in a tough spot. In the old days, we could split the outer tub, take the inner stainless steel drum out, and bolt the paddles down. With modern sealed drums, you cannot do that.

Your only real option to save the machine is to gain access via the sump hose (as described in Method 2). You will need to drill a very careful pilot hole through the drum into the base of the plastic paddle, and secure it using a stainless steel screw. Engineer’s Warning: You must use stainless steel. If you use a standard mild steel screw, it will rust immediately in the wash water and ruin your clothing.

Final Thoughts on Built-in Obsolescence

This four year old machine was written off simply because the manufacturer refuses to provide easy service access or sell the inner drum as a separate spare part. Forcing consumers to buy a £200-£300 sealed drum assembly over a £10 piece of plastic is the definition of built-in obsolescence.

By taking your time and understanding how the locking tabs work, you can easily save your machine from the scrap heap.
