Hot water supply for hot and cold fill machines
Hello
I bought this whirlpool machine a couple of weeks ago: 3LWTW4705FW
It’s hot and cold supply. The appliance specialist who sold me it told me to arrange a hot supply. I did that but it’s off a small electric water heater used for a sink. He fitted the machine. Now there’s an issue with the capacity of the heater as I could smell burning plastic.
Is there any way of telling how big a heater you need to run the machine? The manual isn’t helpful other than pressure figures. Also, could a Y piece be used to make the two inlets use cold supply? I’ve read that this works in other machines.
thank you!

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Whirlpool 3LWTW4705FW can be run from cold supply only
- The problem
- A recently bought Whirlpool 3LWTW4705FW washing machine has hot and cold fill. The installed hot feed came from a small electric sink water heater, which appeared inadequate and the user reported a burning plastic smell. The user asked how large a heater would be needed and whether both inlets could be supplied from cold using a Y piece.
- Likely cause
- The discussion supports that a dedicated hot supply is not required for this machine to operate. No confirmed heater sizing guidance or confirmed fault with the washing machine itself was provided.
- What fixed it
- Accepted advice was that the machine does not need a hot water supply to run. Although it is designed to use hot water ideally, it can be used happily with only one cold water supply. The thread did not document a specific heater upgrade or a confirmed Y-piece installation.
- Checks to try
- Model supplied: Whirlpool 3LWTW4705FW
- Hot feed was connected from a small electric sink water heater
- User reported smelling burning plastic
Safety: Because a burning plastic smell was reported, further diagnosis should be carried out by a suitably qualified appliance engineer if the smell persists.
