Maytronics 99958902-DIY Dolphin Replacement Cable, 40 ft, 2-Wire, No Swivel
Get your Dolphin moving again.
The Maytronics 99958902-DIY (PST-DL99958902DIY) is a 40 ft (12 m) blue 2-wire replacement cable with a DIY motor-side connector for Dolphin robotic pool cleaners. It drops in where the original cable failed, no swivel and no soldering required, so you can revive an E10, Escape, S50, T15, or Active 10 without sending the cleaner out for service. You verify a few model numbers, plug the DIY end into the motor unit, and the cleaner is back on the floor of the pool the same afternoon.
Built for a Clean Swap
You get a genuine Maytronics cable with a pre-molded DIY connector on the motor end, so the repair is a plug-in swap instead of a tear-down. Open the cleaner's motor unit, unplug the failed cable, clip the new one in, and close it back up. There is no soldering, no heat-shrink, and no chance of mis-wiring the two conductors, which is the most common way DIY cable jobs go wrong.
Full 40-Foot Reach
The 40 ft (12 m) length matches the original cable shipped with E10, Escape, S50, T15, and Active 10 cleaners, so the cleaner still covers an in-ground residential pool from the standard poolside power supply position. You keep the same working radius you started with, which means the robot reaches every wall and floor zone it mapped before, no dead spots and no extension cord workarounds.
Diagnostic 2-Wire Build
This is a 2-wire (diagnostic / DIAG) cable, not a 3-wire dynamic cable. The two conductors carry power and basic motor signaling for cleaners that do not rely on a remote control. If your cleaner uses a 3-wire dynamic cable for remote steering or programmed navigation, you need a DYN cable instead. Confirming wire count before you order is the single most important step in picking the right Dolphin cable.
Who It's For
Dolphin E10
Direct replacement for the original 40 ft cable on the Dolphin E10 above-ground robotic cleaner.
Dolphin Escape
Fits the Dolphin Escape above-ground cleaner that ships with a 2-wire, no-swivel cable from the factory.
Dolphin S50 and Active 10
Replaces the OEM cable on Dolphin S50 and Active 10 cleaners that use a 12 m 2-wire DIAG configuration.
Dolphin T15
Restores the original 40 ft working radius on the Dolphin T15 without sending the cleaner out for service.
Why PST Customers Pick This
Genuine Maytronics Part
Original 99958902-DIY cable from Maytronics, not a third-party imitation, so the connector seats correctly inside the motor unit.
DIY-Friendly Install
Pre-molded motor-side plug means no soldering, no crimping, and no shop visit. Most owners finish the swap in under 30 minutes.
Pool-Rated Jacket
Blue marine-grade cable jacket stands up to chlorine, salt, and UV without going stiff or brittle the way generic wire does.
OEM Wire Count
Strict 2-wire DIAG build matches the spec sheet of compatible Dolphin cleaners, so power and signaling behave exactly like the original.
1-Year Warranty
Backed by Maytronics' 1-year replacement-parts warranty when installed in a compatible Dolphin cleaner.
No Swivel Hardware
Cleaner design that omits the inline swivel, fewer mechanical parts in the cable path means fewer long-term failure points.
Compatibility Check
Always confirm your cleaner uses a 2-wire DIAG cable and not a 3-wire dynamic (DYN) cable before installing this part. Plugging a 2-wire DIAG cable into a cleaner that requires a 3-wire DYN cable will disable remote control and can damage the motor unit's control board. Match the wire count to the cleaner model on Maytronics' parts list before powering up.

Frequently Asked Questions
Which Dolphin cleaners is the 99958902-DIY cable compatible with?
This cable is a direct OEM replacement for the Dolphin E10, Escape, S50, T15, and Active 10 robotic pool cleaners that originally ship with a 40 ft 2-wire DIAG cable and no swivel. Before ordering, open your cleaner's parts list or owner's manual and confirm the original cable is a 2-wire build, not a 3-wire DYN build.
What is the difference between a DIAG cable and a DYN cable?
DIAG (diagnostic) cables have 2 conductors and carry power plus basic motor signaling. DYN (dynamic) cables have 3 conductors, the third wire handles remote-control communication and grounding. Cleaners that use a handheld remote or programmed navigation typically need a DYN cable. Using the wrong cable type can disable features or damage the motor unit.
Is the DIY end hard to install?
No. The motor-side connector is pre-molded, so installation is a plug-in swap with no soldering and no crimping. Open the motor unit per Maytronics' published service procedure, unplug the failed cable's connector, plug the new 99958902-DIY connector into the same socket, route the cable through the strain relief, and reseal the motor unit. Most owners finish the job in 20 to 40 minutes.
Can I install this cable myself or do I need a technician?
This is a true DIY part. You need basic hand tools and the cleaner's service manual. There is no live AC wiring involved, the cable runs at the cleaner's low-voltage motor side. If your cleaner is still under Maytronics warranty, check the warranty terms first, some warranties require an authorized service center to perform the repair.
What is the difference between the 99958902-DIY and the 9995862-DIY?
The 99958902-DIY is a 40 ft (12 m) 2-wire DIAG cable with no swivel. The 9995862-DIY is a longer cable with a built-in swivel and is intended for different Dolphin models. Match the part number on your cleaner's parts list, do not assume the longer or swivel-equipped cable is interchangeable.
Does this cable include a swivel?
No. The 99958902-DIY is intentionally a no-swivel cable. The compatible cleaners (E10, Escape, S50, T15, Active 10) were not designed with an inline swivel. If your original cable had a swivel, you need a different Maytronics part number.
Is this a genuine Maytronics cable?
Yes. PST Pool Supplies is an authorized Maytronics dealer, and the 99958902-DIY ships as a Maytronics Certified Genuine Part with the manufacturer's 1-year replacement-parts warranty. Aftermarket cables sold at lower prices often skip the proper jacket compound and the pre-molded connector tolerances, which is why they fail early in chlorinated water.

Beautiful!!
The valve fit perfectly and works great.
Fast shipping and great price!
Does what a small weed- eater would do it minutes versus an hour
Great product does exactly what was advertised to do.
I ordered the wrong part. Customer service was very helpful. I returned it and within the week my credit card was credited back. Excellent customer service policy.
There was a delay in shipping due to postal service. They sent another part right away.
New model 59303 works great, but too bad the last generation Balboa WiFi module 50350 became un-useable.
Exactly as advertised and super fast shipping and delivery
