🔄 LX WE14 Circulation Pump 10-WE14-240 — 1/4 HP 1-Speed 230V — Laing E14 Replacement

Whisper-quiet 24/7 spa circulation — drop-in replacement for the Laing E14 with enhanced seal longevity

♨️ Product Overview

The LX WE14 (Part No. 10-WE14-240) is a 1/4 HP, single-speed, 230V circulation pump manufactured by Lingxiao (LX Pumps), designed specifically as a replacement for the widely used Laing Thermotech E14 spa circulation pump. Engineered for continuous 24/7 operation, the WE14 delivers quiet, reliable water circulation through your hot tub’s filtration and heating system — keeping your spa water clean, warm, and ready to use at all times.

The WE14 features hydraulic performance and port dimensions identical to the Laing E series, with 1-1/2″ MBT (Male Buttress Thread) center suction and side discharge connections. Its adjustable wet end rotates to five different discharge positions (9:00, 10:30, 12:00, 1:30, and 3:00) for flexible plumbing alignment. At just 9.84″ long, 6.06″ wide, and 6.42″ tall, the WE14 fits most existing E14 compartments — though the motor housing is slightly larger than the original Laing E14, so always verify available space before ordering.

Key improvements over the original Laing E14 include a specially designed mechanical seal that resists crystal residue buildup from spa disinfection chemicals (chlorine, bromine, salt), increased motor starting torque to prevent seal friction issues at startup, and high-temperature grease bearings for extended life. The squirrel cage asynchronous motor with Class F insulation, IP55 protection rating, and automatic thermal overload protection ensures safe, reliable operation in demanding spa environments. Used as OEM equipment in Master Spas, LA Spas, Artesian Spas, Clearwater Spas, and many more.

⚠️ Amperage Note — Important: Amperage ratings from different sources vary for this pump:

Electrically, a 230V pump drawing the same wattage as a 120V version should draw approximately half the current. The 120V WE14 (10-WE14-120) is consistently rated at 1.6A across all sources. This suggests the 230V version likely draws approximately 1.0A in actual operation. The 1.6A rating listed by some retailers may reflect the 120V specification being applied to the 230V listing. Always verify the motor nameplate on your specific pump and size your circuit accordingly.

⚠️ Cord and Unions Note: Inclusion of cord and unions varies by distributor. Some distributors include a 48″ AMP-style cord and 1-1/2″ unions; others sell them separately. Confirm with Parts4Tubs at time of order what accessories are included.

⚡ Electrical Requirements

Electrical Spec	Requirement
Supply Voltage	230V (220–240V)
Frequency	60 Hz
Phase	Single
Amperage	1.0A to 1.6A (see note above)
Thermal Protection	Automatic overload (built-in)
Connector Type	AMP-style connector (verify cord inclusion)

⚠️ IMPORTANT:

All electrical work must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local and state building codes.

Hot tubs and spas require GFCI (Ground Fault Circuit Interrupter) protection. A dedicated circuit is required — do not share with other appliances.

This is a 230V pump. Do NOT connect to a 115V circuit. If replacing a 115V Laing E14, verify that your spa controller’s circulation pump circuit is wired for 230V before installing this pump. If your spa uses a 115V circulation pump circuit, order the 120V version (10-WE14-120) instead.

15. Monitor: Keep an eye on the pump and plumbing for the next few days to ensure everything is functioning correctly and that there are no further issues.

Remember that this is a general guideline, and the specific steps may vary based on your hot tub's design. If you're unsure or uncomfortable with any aspect of this process, please do get in touch, happy to help.

How do I know what size hot tub pump I have?

Determining the size of your hot tub pump is an important step when it comes to maintenance or replacement. To find out the size of your hot tub pump, follow these steps:

1. Check the Manual: The easiest way to determine the size of your hot tub pump is to consult the owner's manual or user documentation that came with your hot tub. The manual typically contains detailed information about the specifications and components of your hot tub, including the pump.

2. Look at the Pump Housing: If you don't have access to the manual or it doesn't provide the information you need, inspect the pump itself. Most hot tub pumps have a label or plate on the pump housing that displays essential details, including the pump's model number, manufacturer, and specifications. You can then send that to me or Google it.

3. Measure the Pump: If the label is missing or damaged, you can measure the pump's dimensions. Measure the diameter of the pump's wet end (the part where the water flows) and the length of the wet end. These measurements can help identify the size and capacity of the pump.

4. Consult the Manufacturer: If you can't find the information on the pump or in the manual, contact the hot tub manufacturer or a reputable dealer. Provide them with your hot tub's model and serial number, and they should be able to identify the correct pump size for your specific hot tub.

5. Online Research: You can also search online using the pump's model number or hot tub's make and model. Many manufacturers provide detailed information about their products on their websites, and you may find specifications for your pump model.

Once you have determined the size and specifications of your hot tub pump, you can proceed with maintenance, repairs, or replacement if necessary. Keep in mind that replacing a hot tub pump with the same size and capacity as the original is crucial to ensure proper water circulation and filtration in your hot tub. If you're unsure about any aspect of this process, get in touch, always happy to help.
